OPTIMAL SELECTION OF TARGETS IN THE PRESENCE OF CLUTTER AND EFFECTIVE INTERFERENCE
Staggered blind speeds of MTI radar can be eliminated to a large part by PRF optimization, and the depth of minimum value in the velocity area in the frequency response (|Hs(f)|2) or improvement factor can be optimized with suitable selection of stagger delay (M). When comparing the minimum gain in signal-to-clutter ratio (SCR) and improvement factor, several relative Optima exhibit large discrepancies. Small values of time on target and of radar Frequency with respect to the improvements factor are favored. Among the local optima, some good alternatives can be found that combine high improvements factor and high minimum SCR gain. The use of (MTI) technique, an ideal method to trace the moving targets in RADAR operation system, and utilize the characteristics of special kind of notch filters, via multi adaptive moving targets approach (AMTI).
