基于COMPASS+PD/HRLR组合的侦察导弹对海洋移动目标定位方法研究

Research on A New Method of Moving Target Positioning by Reconnaissance Missile at Sea-Taking COMPASS+PD/HRLR Combination as Foundation

针对现行侦察手段对敌方海洋移动目标进行地理坐标的测量方法不多,测量精度不高的问题,提出了一种利用反舰巡航导弹搭载北斗卫星定位接收机(COMPASS)、合成孔径雷达(SAR)、脉冲多普勒雷达(PD)、高重频激光测距仪(HRLR)、激光测高仪(LHD)与数据传输系统(DCS),实现对敌海洋移动目标准确识别和精确定位的方法,介绍了侦察导弹的组成,说明了定位原理,给出了物理多站连续交会定位算法模型,进行了模拟测量数据解算和误差分析。通过仿真证明,本方法简单、实用,能够满足实际工程应用的需求,可为海上远程精确打击体系提供高精度的目标位置信息。

Addressing the problems that current reconnaissance methods are not only limited in the ways of measuring geo- graphic coordinates of moving targets at adversary sea, but also low in measurement precision, this paper proposes a new method with accurate identification and precise positioning of moving adversary targets at sea. This method is based on anti- ship cruise missile with COMPASS equipped, SAR, PD radar, high repetition laser rangefinder （HRLR）, laser height de- vice （LHD） and data communication system （IX;S）. Also in this paper, the construction of reconnaissance missile is intro- duced, principles of positioning are illustrated, the model of continuous multi-station rendezvous physical location algorithm is established, and the analog measurement data solving and error analysis are completed. Simulation experiments prove that the proposed method is simple and practical that it meets the demands of practical engineering application. It can provide high-precision target location information for long-range precision strike system from the sea.
