Analysis of The Effect of Multiple False Target Jamming Based on CFAR Detection

Multiple false target jamming interferes with radar devices by generating false target signals to mask the echo signals of the true target. It can be seen from the principle of jamming that the false target interval is the key parameter that determines its interference effect. In this paper, the influence of the change of false target interval on the interference effect is deeply analysed through theoretical derivation and simulation verification, combined with the radar constant false alarm rate detection method. The results show that the false target interval determines the number of false targets in the reference cells of the constant false alarm rate detector. By setting different values, it affects the change in the constant false alarm rate detection threshold, thereby enabling effective interference with the radar.
