无源定位各种体制与方法的总结和概述，并做了详细的对比，最后给出源代码及结论(Analyses of the geolocation accuracy that can be obtained from shipborne sensors by use of time difference of arrival (TDOA), scanphase, and angle of arrival (AOA) measurements )

解决非线性规划的工具箱，例子为阻力系数的仿真，方程组的求解，(Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met)

对一个信号文件导入并进行fft变换，显示图形；对信号是否平稳，周期性，采样点数N，有偏无偏处理的估计效果等都做了处理和显示(A signal file is imported and transformed by FFT to display graphics; whether the signal is stable, periodic, sampling point N, the estimation effect of biased and unbiased processing are processed and displayed.)

说明：  首先，在非视距环境中，信号传播将产生多径效应，这将导致对到达时间的错误估计。其次PSO(Firstly, in NLOS environment, signal propagation will produce multipath effect, which will lead to wrong estimation of arrival time. Second, PSO)
