Hata propagation model m-code

this is background subtraction code.

双基（机载）合成孔径雷达测高——比较没技术含量，因为用的方法是斜距差，没用相位差（还没研究出来），所以误差有点大。(Double-base (Airborne) synthetic aperture radar altimeter- not the technical content of comparison, because the methodology used is inclined away from the poor, no phase difference (not finding out), so a bit big error.)

用于二维平面的闭合曲线三次插值，通过给定的几个坐标点，完成闭合曲线的三次插值函数(Closed curve cubic interpolation for two-dimensional plane, through a given number of coordinate points, complete the closed curve cubic interpolation function)

分析了正弦信号分辨率问题，当采样频率相同时，点数越多，分辨率越高，频谱特性误差越小( Analysis the problem of resolution in a sinusoidal signal.When the sampling frequency is the same, the more points,the higher the resolution,and the error spectral characteristic is smaller.)
