摘要
探讨在多目标无源定位情况下 ,采用定位概率计算实施多目标的分选和定位的办法。通过对多目标条件下实例的仿真计算 ,表明在多目标条件下 ,这是一种工程实用的方法 ,具有差错机会少、指示明确的优点。仿真还表明 ,在工程常见的测向误差为 3°的情况下 ,对于偏离载机航线接近 1 0 0km处的目标 ,仅仅采用本文所述的方法 ,可能达到的定位精度大约是 1 0km。
An algorithm based on probability for passive locating in multiple target environment is presented. The research is done through simulation under multiple target environment, which shows it is a good engineering method when facing multi target environment, reaching an easier visible result with less chance of fault. The simulation also indicates, under normal condition of 3 degree DF error, the resulted locating accuracy with this method only for targets almost 100 kilometers away from the trail of the platform aircraft is about 10 kilometers.
