在舰载超视距雷达检测时 ,由于载舰运动所造成的一阶海波谱展宽 ,遮蔽了舰船目标 ,造成目标检测的困难 ,采用空域超分辨处理 ,将目标与展宽的一阶海波谱分开是非常可行的。Constrained -MUSIC算法的分辨性能不受相干目标的影响 ,且在舰载超视距雷达中 ,由于展宽的一阶海杂波谱相应的空间方位是可计算出的 ,Con strained-MUSIC算法可以充分利用这一已知的方位信息 ,将与一阶海浪谱同频 ,但处于不同空间方位的船目标分辨出来 ,有效地实现了高频地波舰载超视距雷达检测下的空域超分辨处理 ,对在舰载雷达情形下有效地进行目标检测提供了一个良好的距离 -速度 -方位分辨后的三维检测背景平台
In the shipborne OTHR detection, due to the first-order sea-wave spectrum broadening caused by the movement of the carrier, the target of the ship is obscured and the difficulty of the target detection is caused. By using the super-resolution spatial processing, the first-order Hyperspectral Spectrum Separating is very viable. The performance of Constrained -MUSIC algorithm is unaffected by the coherent target. In the ship-borne OTH radar, the Con strained-MUSIC algorithm can make full use of the space orientation of the extended first-order sea clutter spectrum This known azimuth information will be the same frequency with the first-order wave spectrum, but in different space azimuths of the ship target resolution, the effective realization of the high-frequency ground wave spaceborne over-the-horizon radar detection space super-resolution processing, Provides a good distance to the target detection effectively in the case of carrier radar - background-velocity-azimuth resolution background detection platform
