Recognition of convoys with airborne adaptive monopulse radar

A technique for recognition of extended targets on the ground, in particular convoys, by air- or space-based radar is presented. The technique is based on adaptive monopulse in conjunction with space-time adaptive processing for clutter and interference rejection. It is demonstrated that the standard deviation of the azimuth and radial target velocity estimates of the space-time adaptive monopulse can be exploited to recognise a potential spatial extension of a moving target.
