摘要

针对机载脉冲多普勒(PD)雷达,介绍了基于距离-多普勒模型的杂波功率谱模型;提出了在中重频(MPRF)工作模式时,同时考虑距离通道和多普勒通道的影响,根据杂波功率谱对杂波进行时域重构的方法;通过仿真得出了杂波的I/Q两路信号,由这两路信号经距离通道划分后进行FFT变换的距离-多普勒二维分布图验证了所提方法的可行性。

Abstract

The clutter power spectrum simulation method based on the range doppler model in the airborne PD radar is introduced. Proposed a new method of time domain singnal reconstruction, which is according to the clutter power spectrum when radar is working on the MPRF state; the range and doppler channel are also considered coinstantaneously. The clutter signal of I/Q channels and the range-doppler 2D distribution have received according to simulation, and the results validated the feasibility of this method.

Key words： range-doppler; clutter power spectrum; clutter reconstruction; coherent vedio simulation
