Randomly interrupted random waveforms

This paper describes the application of randomly interrupted random waveforms in multi-mode radar systems. The work has been motivated by its application to synthetic aperture radars. Conventional SARs use a pulsed waveform, which sets upper limits on the swath width and the cross-range resolution of the SAR. It may be possible to exceed these limits by using a random waveform. In a monostatic system, the waveform must be interrupted to allow reception. To avoid introducing any repetitions into the waveform, these interruptions should also be inserted at random. The paper begins by describing the processing of random waveforms. An iterative processing algorithm is developed, typical results from the algorithm are presented and possible enhancements discussed. Finally, the effects of random interruptions and the potential applications of randomly interrupted random waveforms are described. >
