Research on Clutter Model for Airborne Linear Frequency Modulated Pulse Compression Radar
摘要
Abstract
Compared to the traditional pulse radar,the clutter statistical model for linear frequency modulated (LFM) pulse compression radar has intrinsic special properties because of the superimposed effect.For the airborne radar,the Doppler frequency of echo signal of each clutter cell is different due to the motion of the platform.Relative to the land-based radar,the statistical clutter model of airborne radar is more complicated.In this paper,towards the characteristics of LFM signal and airborne radar,a statistical clutter model suitable for airborne radar that employs LFM waveforms is presented.The new statistical clutter model is analyzed and simulated before and after pulse compressing.The results prove the effectiveness of the proposed model.关键词
