| 摘 要： | 针对强杂波背景下的空中机动目标检测问题，该文提出一种基于非线性最小二乘(Nonlinear Least Squares, NLS)的空中机动目标检测方法。该方法通过构造目标信号模型，并利用NLS算法使其和杂波抑制后的数据具有最小的平方和距离来进行参数估计。该方法在脉冲点数有限的情况下，依然能够获得很好的参数估计结果。仿真结果证明了该方法的有效性。

| Abstract: | In this paper,a method based on Nonlinear Least Squares(NLS) is presented for detecting the maneuvering aerial targets with the strong clutter background.Firstly,the signal model of the target is constructed.Secondly,the data after clutter suppression is obtained.Then,the parameters of the targets can be estimated while using NLS through minimizing the sum of the squares of the distances between the former two.The method can provide an accurate estimate of the parameters even when the data sample is limited.The effectiveness of the method is verified via simulated data. |
