一种基于正方形的摄像机参数标定程序，简单实用(camera calib )

 利用fft()进行快速傅立叶变换，得到频谱，画出正弦函数及其频谱  找出频谱中使得Y轴取最大值时的估计频率记为ft  加入白噪声，绘出信噪比和均方误差的关系曲线 ( using fft () for fast Fourier transformation, spectrum, to draw the sine function and its spectrum  find the spectrum makes the Y-axis maximum value when the estimated frequency is denoted by ft  adding white noise, SNR plot and mean square error curve)

此程序是用来读取C版本星历文件并进行拟合预推处理的，简单可用(the program is used to read C version ephemeris , couple and predict, it is easy and useful)

代码较长但是很清楚的将伪码-线性调频信号和线性调频信号以及GOLD序列信号的频谱图表示出来并最后得出伪码线性调频信号的模糊函数图(Code is longer but it is clear that the pseudo-code- spectrum chirp chirp signals and signals as well as signals GOLD sequence and came to the conclusion that out pseudo-code chirp signal ambiguity function diagram)
