在雷达成像中所用到的多普勒质心估计，用idl语言编写-In radar imaging is used in the Doppler centroid is estimated using idl languages

The function applies the Madsen method for Doppler Centroid estimation. The input are: 1) the raw data, the parameter of the distance between samples in azimuth to be correlated and the PRF (Pulse repetition frequency)

this function is estimate doppler centroid in synthetic aperture radar with ACCC.The basic SAR theory is conceptually simple yet when one looks into the inner workings of the SAR processor it appears quite complicated(The most difficult part of the
