| 摘 要： | 在不增大功率孔径积的情况下,提高星载雷达对微弱空中运动目标检测能力的主要方法是增加积累时间,但卫星平台与目标间的高速运动,使积累时间内有大的距离走动,导致直接相参积累增益下降.同时,目标回波多普勒模糊也是星载雷达目标检测必须解决的问题.为提高目标回波多普勒模糊和大距离走动情况下的相参积累效果,提出预设模糊重数的并行距离...

| Abstract: | Rather than increasing the power-aperture product,long term accumulation can increase the capability to detect dim airborne moving target with space-based radar(SBR).For high velocity between SBR and target,target's range migration will degrade the coherent integration gain.Doppler ambiguity must be resolved for target detection of SBR radar.In order to improve the performance of coherent integration under target's Doppler ambiguity and range migration,this paper presented a long term coherent integration a... |
