Abstract

We discussed a spectral-estimation method, referred to as the PDFT, which was used to overcome the problems of limited k-space data being measured from a monostatic or backscatter radar system. We have also shown how this estimation method can be used to estimate the size of a target, and also how the method permits target recognition to be achieved with only a small amount of backscatter data. That amount of required data points decreases as the information about possible target shapes, expressed by the prior estimate, gets more and more specific
