摘要

调频步进雷达波形通常具有大带宽,由目标逐个频点的RCS电磁计算数据直接重构雷达回波,面临计算量巨大且高速运动目标回波难以实时计算的问题。基于线性雷达目标理论和FFT内插方法,提出了一种调频步进雷达动态目标回波信号生成的新方法,重点解决chirp信号子脉冲高速运动目标回波的实时生成问题。仿真实验验证了算法的有效性。

Abstract

Chirp stepped-frequency radar waveform possesses large bandwidth generally. Echo Reconstruction from electromagnetic computed RCS of each frequency is a computationally intensive task and encounters real time problem for high speed targets. Using linear radar target theory and FFT interpolating method, a new method of dynamic target echo reconstruction of chirp stepped-frequency radar was proposed. The new method focuses on the real-time echo generation of high speed targets under Chirp stepped-frequency pulses. The numerical simulation was performed to illustrate the validity of the proposed method.

Key words： chirp stepped-frequency radar; dynamic target echo; simulation reconstruction; linear radar target theory; FFT interpolating and restoring
