本文介绍采用DMTI串联FFT实现反地物杂波干扰的信号处理系统的初步研制结果。该系统采用了30级台劳加权
旁瓣抑制能力达60dB
主瓣加宽系数小于1.1。本系统探测导弹目标的分辨力达0.6Hz;探测飞机目标的分辨力达0.1Hz。
This paper discusses a specific scheme for realizing the depression of clutter using DMTI in series with FFT.In order to depress the clutter
this system uses Tay-for weighting function with 30 terms. The sidelobe is decreased to -60 dB
the mainlobe widening factor is less than 1.1. The resolution of this system is 0.6 Hz for detecting misstle targets and 0.1 Hz for aeroplane targets.The designed system specifications agree well with the experimental results. This system has been used in an experimental radar system.
