Optimal target detection for marine radars using waveform diversity

Project Summary

Develop novel and low-complexity optimal waveform diversity techniques for small target detection that can adapt to the environment and sea clutter characteristics to minimise the deleterious effects of sea clutter in scan-to-scan integration.

Sea clutter suppression for high-bandwidth marine radars operating at low position on a moving ship can be challenging. The common approach to sea clutter mitigation is to employ scan-to-scan integration. While scan-to-scan integration can help alleviate the masking of radar return signals from a target of interest by sea clutter, it requires a large number of radar scans in low-grazing-angle and high-sea-state situations, and tends to suppress moving targets as well as sea clutter, which is undesirable
