The authors investigate techniques for improving the signal to clutter ratio of an ultra wide-band SAR designed to detect small mine-like objects in the surface of the ground. In particular they collected images with different bistatic antenna configurations designed to cause some decorrelation of the clutter. The images were converted to ground coordinates and then summed. The resulting target strength was then compared with the amplitude distribution of the ground clutter to show the improvement obtained. Whilst some improvement was demonstrated, this was for the relatively easy scenario of targets on the surface partially obscured by grass.
