Scanning policy optimization for LPRF maritime radars

In this work, we study the detection performance of a multi-channel radar system in the presence of sea-clutter. The transmitter adopts a broad beam (whose width is a design parameter), while the receiver forms multiple contiguous narrow beams covering the same region. The key performance measures are derived and the interplay among the width of the transmit beam, the scan duration, the signal-to-noise ratio, and the signal-to-clutter ratio are elicited. Numerical results are provided to show the possible tradeoffs.
