摘要:

从雷达方程的角度讨论雷达作用距离的影响因素。推导了匹配滤波的改善因子,得出了单个脉冲信号的作用距离方程;对比了步进频率信号脉压后和单脉冲脉压信号相参积累后的作用距离;借助计算机仿真对理论推导结果进行验证。

关键词: 线性调频, 步进频, 匹配滤波

Abstract:

The contributing factors to radar-range are discussed based on the Radar-Equation.First,the range equation of the single pulse signal is gained by deducting the improvement factors of match filter.Then,the range after the pulse compression of the frequency stepped radar signal is compared with that after the coherent integration of the signal pulse signal compressed.Finally,the result is proved by simulation.

Key words: linear frequency modulation (LFM);frequency stepped;match filter
