Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guided missile that detects infrared rays or reflected signals generated from a target, and captures and tracks the target. First, I will briefly explain the conventional guided missile (M) of this type. In Figure 1, (M) is a guided missile, (11 is the target that the guided missile (M) captures and tracks, and (2) is the target (1). ) infrared rays or reflected signals (hereinafter collectively referred to as signals) generated from
, (31 is an antenna that receives signal (2) from target (1), (4) is a receiving device that extracts the target signal from the signal received by antenna (3), (5) is the output of receiving device (4) An error signal generation circuit (6) extracts an error signal from the target signal of the target signal, and (6) drives the antenna (3) in the arrival direction of the signal (2) from the target (1) using the error signal output from the error signal generation circuit (5). Antenna servo device f, (71 is a guided missile C by the error signal output from the error signal generation circuit (5)
A steering device that steers M+ toward the meeting point with target (1).

(8) is a lower side antenna that receives the signal (2) from the target (1) when the guided missile (M) passes near the upper side of the target (1).

(9) is an upper side antenna that receives all signals (2) from target (1) when guided missile CM) passes near the lower side of target (1).

(10) is the left side antenna that receives all the signals (2) from the target (11) when the guided missile (M) passes near the right side of the target (1).

(111 is the right side antenna that receives all signals (2) from the target (11) when the guided missile (M) passes near the left side of the target (II).

α is the target signal output from the receiver (4) and the signal (2) from the target (11) received by the lower side antenna (8) or the upper side antenna (9) or the left side antenna (101 or the right side antenna + Ill). The proximity fuze circuit, o3, generates a proximity detonation pulse when the guided missile (M) passes near the target (11). Sending tube, a (a) is a proximity fuze (proximity detonation pulse of output 121) or a detonation signal that generates a detonation signal that detonates ammunition 05 when the arrival tube (proximity detonation pulse of output 13+ is output) When the generation circuit 1 (151 is a guided missile CM) passes near the target (4+) or hits it directly, the ammunition 9061 is detonated by the detonation signal output from the detonation signal generation circuit I and causes great damage to the target (1). is a propulsion device that provides thrust to the guided missile (M).The conventional guided missile (M) is configured as described above. Finally, when the guided missile (M) passes near the target (fil) or when the guided missile (M) passes near the target (fil), the 1jijj drug Q51 is detonated and the missile is guided to the meeting point of the target (!). Inflict great damage against l.

However, with conventional guided missiles (M), under electronic warfare environmental conditions and conditions with poor anti-clutter reflection, each missile is received at <8) to 01). B;) Because the synchronization level is high, a proximity detonation pulse is generated in the proximity fuze circuit (121), and as a result, the guided missile (M) can detonate the ammunition [+51 early detonation 1-] before reaching the meeting point with the target +11. To do so.

This was hindering the ability of guided missiles (M) to shoot down targets (11).

In addition, since conventional guided bullets (Ml ammunition (15)) were omnidirectional, they detonated at the meeting point with the target, and even in this case, one bullet would cause damage to the target. The effectiveness of ammunition has been a problem because it is not fully functioning, but only partially functioning.Especially in recent years, small and
There is a strong interest in improving the ability of guided missiles (M) to shoot down targets (11) under poor radio wave environment conditions such as the town, N conversion, elimination of unnecessary functions, and poor radio wave environment such as in the siege of the battle.

The above drawbacks have become important issues. This invention is characterized by improving the above-mentioned drawbacks, and includes a receiving device (4).
The output of the newly provided #1/+ component described later is input to the newly provided component described later to control the received signal received by each side antenna (8) to Ql+ of the guided missile (M'). This prevents the early detonation of the guided missile (M') by not generating the proximity detonation pulse until it meets the target (11) even under poor radio wave environment, and at the same time prevents the guided missile (M') from early detonation even when it passes close to the target (11). , controls the effective direction of directional ammunition, which has been replaced with conventional omnidirectional ammunition, to be directed toward the target.

By precisely making the ammunition ultra-thick when meeting the target,
This improves the ability of the guided missile (M') to shoot down the target (1). The guided missile (M') of the present invention will be explained below with reference to FIG. 2, which is a specific example.

α An antenna angle detection circuit that detects whether the antenna facing the target direction is downward, upward, leftward, or rightward with respect to the flight attitude of the guided missile and generates a signal corresponding to each direction ( 19 is the target (1) from the output of the receiver (4).
), and determines whether or not a predetermined time has elapsed by dividing the meeting time, and outputs a high level signal if the predetermined time has elapsed, and outputs a low level signal otherwise. , 121j outputs the output of the antenna angle detection circuit (I81 as it is) when the output of the operation period determination circuit α9 is a high level signal, and outputs the output of the antenna angle detection circuit (I81 as it is) when the output of the operation period determination circuit α9 is a low level signal. The side antenna 0N10FF signal generation circuit that outputs a low level signal without outputting the output of 1+11, This is the output of the antenna angle detection circuit (2).When a signal corresponding to the antenna direction (downward, upward, leftward, or rightward) is output from the side antenna ON/OFF signal generation circuit, the direction A side antenna receiving circuit that outputs only the signal received by the side antenna and does not output any other signals (22+ is a control circuit that outputs only the signal received by the side antenna of Corresponding to the output signal I, a control signal is output for directing the effective detonation direction of the directional shield 111 toward the target direction, and when the output of the 1-operation period determination circuit (I~ is a low level signal,
The rotation angle control signal generation circuit (C3) outputs a control signal la (/) * The rotation angle control signal generation circuit (C3) uses the output of the rotation angle control signal generation circuit (22) to direct the effective bursting direction of the directional ammunition toward the target direction. Installation↑L'¥: +(24) is the rotation angle control servo device 23)? Koyori 5j? It is a directional ammunition whose loading direction is controlled to point towards the target.

This invention is configured as described above.

In addition to being able to prevent early detonation in adverse radio environment conditions such as electronic environments, the J-type ammunition, which is more powerful than conventional ammunition, can be used to attack targets with full force, making guided missiles more effective. Objective (1) of (M'): It is possible to improve the attacking ability. In addition, it is expected that by adopting J) A reversible ammunition, it will become a small and light vehicle.In addition, in the example, ++81-(c) is shown as an independent circuit and device, but this 1Qli~ (It goes without saying that it can be replaced with a single component with 23+ functions.
