摘　　要：研究空中机动目标参数估计优化方法。在进行被动式空中机动目标跟踪过程中,由于空中环境干扰较大且机动目标信号具有一定的隐蔽性、多样性,采用传统的算法进行目标参数估计,跟踪的精确度不高,严重影响跟踪效果。为此,提出基于改进非线性最小二乘的空中机动目标参数估计优化方法。针对机动目标相关参数数据进行降维处理,以减少跟踪过程的计算量,依据改进非线性最小二乘理论,构建目标信号模型,从而确定目标搜索范围,构造代价函数,获取参数估计结果,实现对空中机动目标的有效检测与跟踪。实验结果表明,利用改进算法进行空中机动目标参数估计优化,能够获得较好的目标参数估计效果,提高空中机动目标跟踪的准确率。The research air maneuvering target parmneter estimation method.
