Uncertainty Product Scattering Function Estimation

Abstract

A new concept for the estimation of scattering processes in the delay-Doppler (phase) plane has been proposed. It reduces ambiguity self-clutter effects by forming a test statistic from the product of two auto-uncertainty functions generated by the transmission of two separate waveforms. These must be transmitted in close temporal proximity yet should be disjoint in the sense that their cross-uncertainty function is required to have minimal support close to the origin. Initial results indicate that the technique produces much cleaner estimates of the scattering process with much less of the sidelobe effect normally experienced with large TW signals.
