    Because the signals of the target reflections are coherent, the reconstructing matrix algorithm which uses the time-shift correlation method is studied. Not only has it the good ability to solve the coherence problem, but it also reduces the computation because of the time-shift correlation instead of the eigenvalue decomposition.

A simplified auxiliary channel approach is proposed. The number of auxiliary channels is reduced from N+K-1 (Klemm' method) to 4~6 typically, so that the computational load is greatly reduced, which make its implementation possible in real time in near future. The gain in signal/ clutter-plus-noise ratio is almost identical to that obtained by using Klemm's method. Theoretical analysis and simulation results comfirm the above conclu- sions.

提出了一种用于相控阵机载预警(AEW)雷达杂波抑制的简化辅助通道法,这种方法与Klemm提出的辅助通道法相比,采用的辅助通道数从N+K-1个[N为天线阵元(或列子阵)数,K为相干处理脉冲数]减少到4~6个。其性能与Klemm方法基本相同,而运算量大大减少,使实现成为可能。

Abstract:Coherent signal processing in many classes of airborne radar systems is limited bythe metheds used to compensate for platform motion。 pletform motion causes doppler shifts of re-turns which vary with the angle between the velocity vector and the scatterer.

Abstract:Coherent signal processing in many classes of airborne radar systems is limited bythe metheds used to compensate for platform motion。 pletform motion causes doppler shifts of re-turns which vary with the angle between the velocity vector and the scatterer. Because of the fi-nite antenna beamwidth and finite transmitted pulse length,the returns from many scatterers arereceived simutaneously。 These returns have different doppler ahifts which reault in a spectrum ofreceived doppler frequencies, This spectrum degrades the pedormance of radar systems that co-herently process these returns。Time Average Clutter Cohereent Airborne Radar(TACCAR)is a widely used technique tocompensate for the component of motion which is paraliel to the axis of the beam。 This report evaluates TACCAR in terms of its improvement to moving target indicator(MTI)performance。 It Isshown that MTI performance can be improved signi fican tly with extensions to th e TACCARconcept。

很多机载雷达系统的相干信号处理都受到平台运动补偿方法的限制。平台运动引起回波多普勤漂移,它随着速度向量和散射体间的夹角而变化。由于天线波束和发射脉冲都有一定的宽度,因而会同时收到许多散射体的回波。这些回波有不同的多普勒漂移,会形成回波信号的多普勒频谱。形成这个频谱后会降低相干处理雷达系统的性能。时间平均杂波相干机载雷达(TACCAR)是广泛应用的技术,用此来补偿与波束轴平行的运动分量,本报告根据其改善动目标显示(MTl)性能的程度对它进行了评价。说明了在TACCCR概念的范围内,大大提高了MTI的性能。

The mechanism of the performance degradation due to coherent interferences in convertional adaptive array is investigated. Based on decorrelating the incoming coherent interference signals, a technique of coherent interference suppression in adaptive circular array is proposed. Theoretical analysis and computer simulation results prove that the technique is correct and useful.
