摘要
针对IRST和雷达数据融合 ,提出了一种协调决策方法 ,用以解决如何减少雷达被对方ESM锁定的机会 ;当雷达关断后 ,如何获取目标的位置信息 ;如何检测目标机动等问题 .首先构造了用于在雷达关断后预估目标状态的时间多项式 ;其次通过比较预估值和来自IRST的目标观测值建立了一组检测目标机动的判别式 ;且给出了一组决策规则 .最后对给定的目标环境进行了模拟仿真 。
A new synergy decision method for radar and infrared search and track (IRST) data fusion is proposed, to solve such problems as how to decrease opportunities for radar suffering from being locked on by adverse electronic support measures (ESM), how to retrieve range information of the target during radar off, and how to detect the maneuver of the target. Firstly, polynomials used to predict target motion states are constructed. Secondly, a set of discriminants for detecting target maneuver are established by comparing the predicted values with the observations from IRST. Thirdly, a set of decisions are presented. Lastly, simulation is performed on the given scenario to test the validity of the method.
