Analysis of the Effect on Radar Low Elevation Angle by Wavebeam Splitting

This paper base upon the phased array radar theory of radar wavebeam and theory of single pulse, analysis on the effection of angle-sensitivity function by wavebeam splitting , and low angle treking quality of S band phased array radar by multipath effect. We compare the reality and possibility about several kinds of approaching trcking quality such as bias axis tracking and complex angle technique on low-elevation angle object.
