Abstract

PURPOSE:To perform jamming against electric wave sources different in frequency in a time-sharing manner by one variable oscillator, by constructing an apparatus so that the transmission frequency of a jamming wave can be altered every specified time. CONSTITUTION:A reception frequency detecting circuit 2 detects different frequencies from a plurality of electric wave sources and sets a jamming transmission time for each of the electric wave sources. A memory 5 stores each frequency and each jamming transmission time sent from the detecting circuit 2. A control circuit 6 for transmission data reads a prescribed frequency and a prescribed time stored in the memory 5, according to an address, and sets and outputs the prescribed time. A variable oscillator 8, supplied with an output from the control circuit 6, oscillates a transmission wave of the prescribed frequency. A timer 8 is supplied with an output of the set time from the control circuit 6 and outputs an interrupt signal to the control circuit 6 at a prescribed point of time passing. The address is renewed in response to this interrupt signal. By this constitution, the electric wave sources having different frequencies can be jammed in a time-sharing manner by using one variable oscillator.
