Analysis of the General Electric Monopulse Clutter Rejection Technique
Abstract
The 'monopulse' technique attempts to obtain signal-to-clutter (S/C) improvement on point targets in distributed clutter by processing returns from two monopulse antenna beams (over and above the S/C improvement due to conventional MTI techniques). A theoretical upper bound on S/C improvement is derived here for the general class of systems which process returns from multiple beam positions. The maximum possible improvement is small, being only 1.25 db for a sin x/x antenna pattern and 2.85 db for a sin squared x/x squared antenna pattern. GE's own computations, when correctly interpreted, indicate an improvement of from 0.3 db to 0.6 db (based on a sin x/x antenna pattern), in agreement with the theoretical upper bound obtained here.
