PURPOSE:To obtain a radar jamming apparatus having a simple constitution by obtaining radar jamming signals in an electronic way by using pattern signals having similar amplitude variations to those of aerial radiation patterns in place of an aerial. CONSTITUTION:By generating signals similar to aerial radiation patterns in an electronic circuit, a radar jamming apparatus can be constituted without rotating an antenna. That is, high-frequency pulse signals generated by an oscillator 4c are given to a modulator 4a and modulated therein by pattern signals generated from a pattern signal generator 4b, and become jamming signals. These jamming signals are amplified by a power amplifier 4, given to an aerial 1, and radiated in the air. |
