摘　　要：为了研究相位编码雷达的干扰效果,针对间歇采样转发干扰只能产生单一、滞后假目标的不足,提出了基于随机码元调制的密集假目标干扰方法.该方法将间歇采样信号经过码元调制后再转发出去,干扰通过雷达脉压处理后形成密集假目标.由于调制码元是随机产生的,假目标出现的位置和幅度也将是随机的.仿真结果表明,经改进后的干扰方法所产生的密集假目标同时包含了超前假目标和滞后假目标,不同的调制码元能够产生不同的假目标.To study the effect of jamming against the phase-coded radar, this paper puts forward a jammingmethod of dense false targets based on the random code modulation, for the drawback that the interrupted-samplingand repeater jamming can only generate a single and lagged false target. In this scheme, the interrupted-samplingsignals are transmitted after being code modulated, and the dense false targets are formed by the jamming afterbeing radar pulse compression processed. And the position and amplitude of the false targets would be randomas the modulation code is generated at random. Simulation results show that the dense false targets generated usingthe improved jamming method include both the forward false targets and the backward ones, and the differentmodulation codes could generate accordingly different false targets.
