Abstract: On the basis of the working principle and circuit response characteristics of the millimeter-wave (MMW) alternating current radiometer, a novel method for waveform jamming is proposed. In this method, a MMW jamming source is used to transmit the narrowband signal as the heat source and then a wide-time signal is obtained through a broadband reception and detection of the radiometer. Next, the wide-time signal excites differential response of low-frequency circuit of the video amplifier to yield the splitting waveform, which is similar to the negative pulse waveform in metal-target detection, therefore achieving detection effect of cold-target from the angle of waveform simulation. Simulation results show that the average similarity of the simulation waveform and the actual waveform is 79.21%, and the processing results of experimental data demonstrate validity and feasibility of the proposed method.
