摘要

影响舰载雷达探测误差主要为平台导航定位误差和传感器自身探测误差,针对对这两类误差的影响因素进行了分析,首次综合考虑这两种系统误差,提出了一种基于正则化的多平台导航定位及探测偏差估计方法,利用不同舰艇上传感器对公共目标探测的迭合条件,建立系统误差观测方程,利用LS对两种系统误差同时进行了估计,并在偏差估计中采用正则化估计方法,提高估计结果的稳定性,最后进行了仿真验证,仿真效果验证了算法的有效性,具有较高的工程应用价值.%The ship navigation positioning biases and sensor's detecting biases is the key factor affecting the quality of ship-borne radar detecting. We first comprehensive account of this two kinds of biases, analyzed the affect of sensor detecting biases ans ship navigation positioning biases, proposed one kind biases estimation algorithm based on regularization method, the use of different ship target detection sensor on the superposition of the public target, establishment of biases obervation equation, and use regularization method in bias estimation, Improve the estimation stability, then used LS to estimate the biases, the simulation results varify the validity of the algorithm, it has a high vallue of engineering applicaton.
