| 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。

| Abstract: | 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. |
