Abstract
The clutter suppression capability of frame difference filtering using staring arrays is evaluated. With the assumption that the sensor platform is at low altitude, the efficacy of the filter on terrain clutter is determined analytically using the standard frequency domain approach. The dependences of the clutter suppression factor on such parameters as platform velocity, altitude, slant range, sensor field-of-view, and frame time are determined. The frame difference filter is also evaluated for a stationary sensor observing an explicitly time dependent clutter source.
