Clutter Cancellation for Airborne Passive Radar Based on RDNLMS

摘要

摘要: 該文利用RDNLMS算法對(duì)消機(jī)載外輻射源雷達(dá)多普勒展寬的直達(dá)波、強(qiáng)雜波，推導(dǎo)了RDNLMS濾波器的傳遞函數(shù)，在此基礎(chǔ)上提出一種非均勻多普勒頻率抽取方法，在降低計(jì)算量的同時(shí)盡可能減小了因抽取帶來的性能損失。該方法既能確保強(qiáng)雜波落在所抽取的多普勒頻率上從而被有效對(duì)消，又能保證抽取間隔不致過大進(jìn)而使較弱的雜波也得到適當(dāng)?shù)囊种啤７抡鎸?shí)驗(yàn)表明：當(dāng)對(duì)消階數(shù)相同時(shí)，非均勻多普勒頻率抽取方法比均勻抽取對(duì)消性能提高2.4 dB。

Abstract: RDNLMS algorithm is used to cancel Doppler-spreading direct signal and strong echo of airborne passive radar. The transfer function of RDNLMS filter is deduced, based on which a method of non-uniform Doppler extraction is developed to decrease the computing load while minimizing performance loss. With this method, the Doppler of strong echo will be surely extracted hence strong echo will be cancelled efficiently. In addition, the interval of extracted Doppler will not be too large to offer proper suppression for weak echo. Simulations show that when the order of RDNLMS filter is fixed, the performance of non-uniform Doppler extraction will be 2.4 dB better than the uniform one.
