Clutter maps formation in monostatic primary radar

In this paper a method of clutter maps creation for the Doppler filtering of undesirable echoes in monostatic primary radar is presented. A described algorithm of the received data analysis leads to clutter maps of two types. The first one is a ground clutter map used for stationary echoes cancelation using a standard MTI filter. The second one is a map of the meteo-clutter suppressed by the AMTI filter, where a Doppler frequency estimate is stored in parallel.
