摘要
载机在空中的任何机动行为都会使多卜勒波束锐化（ＤＢＳ）性能下降，严重时甚至失效。针对ＤＢＳ工作特点，对所需的运动补偿方法，进行了深入的分析与研究，给出了运动补偿的一般方法，同时还提出了一种新的用载机在雷达视线（ＬＯＳ）上的投影速度来实时控制脉冲重复周期（ＰＲＦ）的相位补偿方法，并对该方法的精度及其对惯导系统（ＩＮＳ）的容差范围作了分析。最后给出了模拟结果。
Any platform motion error,which is defined as the error between the actual flight path and the nominal one,can degrade the perfonnanee of Doppler Beam Sharping(DBS),even mak-ing DBS fail to work.The method of motion compensation for DBS is deeply analysed and stu-died,and a general motion compensation scheme is deseribed.A novel method of phase compen-sation in DBS is proposed,which compensates the echo phases by adjusting Pulse Repetition Frequency(PRF)according to the velocity projected on the light of sight(LOS).Besides,the tol-erance of the method is also analysed.At last,the results of simulation are given.
