摘要
针对线性调频脉压雷达全脉冲采样直接转发干扰中假目标间距过大的问题,分析了典型的3种密集假目标干扰方法:间歇采样直接转发干扰方法、全脉冲采样延迟叠加干扰方法以及全脉冲采样分段叠加干扰方法的干扰时序设计和信号处理方式,研究了不同干扰时序以及信号处理方式对脉冲压缩后产生假目标的数目和密集度的影响,并结合仿真从干扰效果角度比较了3种干扰方法的优缺点。
In order to improve the jamming effect of whole sampling retransmission jamming for linear frequency modulation pulse compression radar, which makes the distance between false targets too great, the jamming time sequence and signal processing mode of the three typical dense false target jamming methods, including the intermittent sampling retransmission jamming method, the whole pulse sampling delay stack jamming method and the whole pulse sampling sectional stack jamming method, are analyzed. Moreover, the influence of the jamming time sequence and signal processing mode on number and density of dense false target are studied. After the jamming effect of three different jamming methods simulated, the advantages and disadvantages of these methods are compared and evaluated.
