Aspects of Non-Identical Multiple Pulse Compression

Some radar systems utilize pulse agility to achieve higher range resolution or mitigate range ambiguities. However, transmitting different waveforms on a pulse-to-pulse basis can have deleterious effects when traditional pulse Doppler processing is employed. In this paper a non-adaptive technique, entitled Non-Identical Multiple Pulse Compression (NIMPC), is derived that facilitates pulse-agile clutter cancellation and is readily implementable via fast convolution techniques. The new method is extended to account for clutter Doppler spread as well as multiple range-ambiguous clutter intervals. NIMPC is assessed via simulation of a synthetic wideband pulse train.
