Abstract:

The monopulse technique attempts to obtain signal-to-clutter SC improvement on point targets in distributed clutter by processing returns from two monopulse antenna beams over and above the SC improvement due to conventional MTI techniques. A theoretical upper bound on SC 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 xx antenna pattern and 2.85 db for a sin squared xx squared antenna pattern. GEs own computations, when correctly interpreted, indicate an improvement of from 0.3 db to 0.6 db based on a sin xx antenna pattern, in agreement with the theoretical upper bound obtained here.
