摘要
本文分析阐述了利用脉内调频、脉间跳频技术获取距离高分辨一维成像的可行性 ,导出了静止目标和运动目标的回波表达式 .根据线性调频子脉冲的回波表达式 ,详细分析了运动目标回波对信号处理器采样位置的要求 .
This paper analyzes the technology with intra-pulse chirp and inter-pulse stepped frequency to obtain high-resolution range profile.The echo expressions of static and moving targets are derived.According to the echo expression of chirp-subpulse signal,the sampling position requirements of signal processor are discussed.
