Moving target indication in the presence of radio frequency interference
Abstract
Moving target indication (MTI) is greatly complicated by the presence of radio frequency interference (RFI) which 'rings' the MTI filter causing false alarms. This effect is particularly important in radars with a limited number of coherent bursts on target. A subclutter RFI processing (SRP) technique has been developed to allow effective MTI processing in the presence of impulsive RFI. This technique does not have the sensitivity gap characteristic of conventional 'RFI detectors'. Thus, RFI induced false alarms can be effectively eliminating while still maintaining useful subclutter target visibility. The SRP technique has been analyzed by Monte Carlo simulation and by experiments conducted with recorded coherent radar signals.
