【摘要】 首先分析了不同距离高分辨宽带雷达信号波形的回波模型。针对其中的调频步进距离高分辨雷达信号这一特殊信号形式 ,提出了一种基于ADSP2 10 6X的雷达视频信号模拟器。该模拟器能够实时模拟调频步进宽带单脉冲雷达三通道I、Q信号 ,并具有角支路闭环功能 ,已成功地应用于某雷达系统的测试和调试中更多还原

【Abstract】 The echo models of different high-range resolution (HRR)broadband radar signals are analyzed in this paper. Aimed at the modulated frequency stepped radar signal,a radar video signal simulator based on ADSP2106X is advanced. It can simulate the real-time I and Q signals of the three channels of modulated frequency stepped broadband single-pulse radar,and has the closed-loop function of angle channel.This simulator has been applied in the test and debug for some radar system successfully.\;更多还原
