Abstract:

The velocity filter is a variation of the 3D matched filter. Velocity filtering applies a constraint in the form of assuming that targets will have a constant velocity over the integration period of the filter. Velocity filters are applied over multiple frames of data and are able to detect low Signal-to-Noise Ratio SNR targets that would otherwise be undetectable using conventional single look detection techniques. This report derives, discusses and assesses the performance of the velocity filter technique.
