摘要
有限区域内多目标的相互干扰是定位系统目标识别所面临的难题之一。分析了影响空域识别能力的各种因素,提出了利用等张角曲面、等倾角倒圆锥曲面多重交集投影方法,解算识别距离及形态,实现了空域识别有效性定量评价。指出了目标数量、间距、布阵及传感器空域分辨能力、侦测接近倾角等与有效识别距离及形态的变化关系,对充分发挥传感器探测效率和选择侦测方位提出了一条有效的技术途径。
Mutual interference multi-target in limited region is an obstacle to target-recognition of detection system. Different factors affecting distinguishability in space domain are analyzed. With the intersection of multiprojection of equal angle curved face, and up-side-down equal pitch conic surface, the recognition distance and distribution figure are reckoned, and quantitative evaluation of distinguishability in space domain is implemented. Variation relation is found between validity recognition distances as well distribution figure and number of radiant source, distance between radiant sources, embattle of radiant source, resolution capability in space domain of sensor, approaching pitch of sensor. An effective technique approach is presented to elevate the detection efficacity of sensor, and to choose detection direction.
