探讨了在选程雷达中,由于高工作因数波形引起的部分回波蚀损,并指出有两个蚀损区。研究了增大距离旁瓣对杂波电平的影响,以及对信号噪声比、脉冲宽度与脉冲幅度的影响。文中指出,由于蚀损所引起的增大距离旁瓣以及所造成的杂波效应,不会延续到蚀损区以外。进一步指出,可预计到相控阵雷达能在第一个蚀损区内满意地工作,此区延续的距离等效于发射脉冲宽度,并指出雷达设备的测量距离能有效地延伸到对应于重新开始发射的距离以远。
In the process of range selection, some echo erosion caused by the high duty cycle waveforms is pointed out, and two eroded regions are pointed out. The effect of increasing the distance sidelobe on the clutter level and the effects on signal-to-noise ratio, pulse width and pulse amplitude are studied. It is pointed out in the paper that due to the increase of the side lobe caused by the erosion and the clutter effect caused, it will not extend beyond the damaged area. Further pointed out that phased array radar can be expected to work satisfactorily in the first erosion zone, the continuation of this zone is equivalent to the launch pulse width, and pointed out that the measurement distance of the radar equipment can be effectively extended to correspond to the re- Began to launch a long distance.
