摘要
介绍了红外侦察告警系统被动测距原理,针对双站被动测距方法的局限性,研究了三站被动测距方法。结合实际应用需要,分析了影响该测距算法测距精度的因素,并给出误差计算公式。给定条件下计算机仿真结果表明,三站被动测距具有很好的实用性,可实现对目标0°～360°全方位高精度测距。
The principle of passive range measurement based on IRST system is presented. Aiming at the limitation of double-station IRST system, a passive range measurement with triple-station IRST system is introduced. Combining with actual application, the algorithm measurement precision is analyzed, and the error formula is given. The simulation results show that the passive range measurement with triple-station IRST system has good practicality, which could complete fine ranging from 0° to 360°.
