This paper will detail the approach for detecting moving targets in ultra high frequency (UHF) FOPEN systems. It is well known that a moving platform provides competing clutter spread in Doppler that masks all but the very fast ground targets. Moving target detection RADARs have been developed at UHF for detecting airborne targets. For ground moving target detection, the competing ground clutter can be canceled by adaptive processing and multiple antenna phase centers. However, a very large antenna is required at UHF to provide both accurate target location and to minimize the clutter masking of targets. These requirements will be explored in terms of the ability to achieve an acceptable minimum discernable velocity (MDV) and their impact on the RADAR design.
