In this chapter, we present a time-reversal implementation of a transmit waveform preconditioning scheme for optimal clutter rejection in radar imaging is presented. Waveform preconditioning involves determining a map on the space of transmit waveforms, and then applying this map to the waveforms before transmission. This work applies to antenna arrays with an arbitrary number of transmit and receive elements, and makes no assumptions about the elements being co-located. By our time-reversal implementation we avoid the need to obtain an explicit model for the environment in order to compute the preconditioning operator.
