1. A non-transitory computer-readable medium comprising instructions stored thereon, which when executed by at least one processor, configure the processor to perform operations comprising:

  • transmitting a plurality of radar pulses by a non-coherent radar toward an area of interest;

    receiving a radar return scattered from the area of interest, the radar return including a return from a target and interference from system noise and background noise and clutter; and

    processing the radar return for at least one range-azimuth resolution cell in the area of interest to differentiate the return from the target from the interference from the system noise and background noise and clutter, the processing including;

    applying at least one threshold to differentiate the target from the noise and system noise and the background clutter;

    comparing the radar return to a first threshold of the at least one threshold, the first threshold set at a level to identify multiple radar contacts including the target and false contacts from the interference from system noise and background noise and clutter, wherein a radar contact is declared when the radar return exceeds the first threshold; and

    tracking the multiple radar contacts over time to distinguish the target from the false contacts.
