レー・レーダー試験装置。 A device that generates a simulated reflected signal when radio waves transmitted from a phased array radar to a target are reflected from the target.
In order to give the pseudo target signal a motion according to the beam angle of the radar, a speed information signal, a distance information signal, a beam scanning angle signal, and a reference signal are input as pseudo target information from an external device, and the above speed information is input. A Doppler generator that receives the signal and generates a Doppler signal as a pseudo target signal, a mixer unit that receives the reference signal and connects to the output end of the Doppler generator, and a mixer that receives the distance information signal and generates a delay time of the pseudo target signal. a pulse modulation section connected to the output end of the mixer section and the output end of the delay circuit section to perform pulse modulation; and a pulse modulation section that receives the beam scanning angle signal and generates a pseudo target signal according to the beam scanning angle. a first calculation section that determines the output level; a control section that is connected to the output terminal of the first calculation section and controls the output level of the pseudo target signal; and an output terminal of the pulse modulation section and the output of the control section. In a phased array radar test equipment consisting of a variable attenuation section connected to the end and changing the output level of the pseudo target signal, it receives a beam width signal from an external device and adjusts the output level of the pseudo target signal according to the beam width. 1. A phased array radar testing device characterized in that a second calculation section for determining the above is added, and an output terminal of the second calculation section is connected to the other input terminal of the control section.
