Scatterer excursion compensation in sequential radar image projections

Summing of registered radar images, taken from multiple aspects, can be extremely useful for target recognition of both human and automatic kinds. Combining the imagery, however, is not straight forward, when the imagery is taken under varying imaging geometries, - that is with varying radar elevation (grazing angle), squint and bistatic angles, for example. This paper addresses the problem of combining high elevation turntable imagery, where the target projection in the radar images can vary substantially. The mathematics developed here, however, can be generalized in a straightforward manner to the other radar modes, as will be described below. A method of focusing scatterers at given heights is found and demonstrated.
