随着科学技术的发展日新月异，红外侦察设备已越来越广泛地应用于机载平台。典型机载红外设备红外传感器和激光传感器作用距离存在着明显的不匹配问题，对超远距离目标无法精确定位。为实现距离缺失条件下远距离或超远距离目标的高精度定位，提出了多平台协同探测无源定位方法。仿真结果表明，多平台协同探测无源定位算法可有效实现高精度目标定位，其定位精度约为7%R，优于传统到达时差定位（TDOA）和到达方向定位（DOA）等方法。
Abstract
With the rapid development of science and technology, the infrared reconnaissance equipment is widely used in airborne platforms. There is an obvious mismatch in operating distance of infrared sensor and laser sensor in typical airborne infrared equipment, which can't accurately locate the ultra-long distance targets. In order to realize the high precision location of long distance or ultra-long distance targets under the conditions of distance deletion, the method of passive location based on multi-platform collaborative detection was proposed. The simulation results show that the passive location algorithm based on multi-platform collaborative detection can effectively realize the high precision targets location, and the location precision is about 7%R, which is superior to that of traditional TDOA and DOA methods.
