Research on the Detection of the Multiple Unresloved Targets Based the Monopulse Radar
Atr La · Signal Processing · 2005
When the returns come from two or more unresolved targets interfere (the signals are not resolved in the frequency or time domains ) in a monopulse radar system, the direction-of-arrival (DOA) estimate indicated by the monopulse ratio is not the true information of the tracked target. Then the tracking systems is influenced. In literature [1], An approach has been proposed to detect whether the returns come from a single target or two unresolved targets. Here the above approach has been extended from two to N unresolved targets.The simulation indicates that the detection probability under the N unresolved targets is not sure to exceed that under the two unresolved targets ,which is easily affected by the SNRs of the two target which are separated most among the N targets.
