摘要
给出了一种相关干涉仪测向的改进算法。与在全方位范围内进行相关运算的常规相关干涉仪不同,它只在相位角的有限区间内进行相关运算并搜索最大相关系数值,可以极大的缩短相关干涉仪测向所需的时间;在该方法中引入曲线拟合算法对相关运算后的数据进行处理,可以使相关干涉仪测向系统获得更高的测向精度。
This paper presents an improved algorithm for correlating interferometer direction finding. Unlike the conventional correlating interferometer which calculates the correlation coefficients in the entire range of azimuth angle, the improved algorithm does this only in finite interval and searches the maximal correlation coefficient, thus shortening the time the correlating interferometer needs in direction finding dramatically. Using curve fitting method to process the data after correlation operation can further improve the direction finding accuracy of correlation interferometer.
