| 摘 要： | 针对中重频PD雷达应用背景,设计了一种主瓣杂波抑制滤波器。对主瓣杂波在实际情况下的参数特点进行了详细分析,得出杂波强度、带宽和功率与俯仰角的对应关系,据此提出了采用查表法设计主瓣杂波抑制滤波器方法;该方法克服了对消器和AMTI滤波器的不足,能有效改善杂波抑制性能,其算法存储容量和实时性满足设计要求,具有良好的工程应用价值。

| Abstract: | In view of application of medium pulse repetition frequency pulse Doppler(MPRF PD) radar,a main-lobe clutter suppression filter is designed.Characteristic of main-lobe clutter parameters in real situation is analyzed in detail;relationship between clutter intensity,bandwidth and power with elevation angle is obtained;and a design method of main-lobe clutter suppression filter with looking up table(LUT) is proposed.By using of the LUT method,deficiencies of traditional canceller and AMTI filter are overcome ... |
