Abstract

This paper details the use of the Radon transform for improving small target detection in a marine environment by radar. The data used were collected using a 150 GHz radar that stared at anchored targets in a wave tank which simulated maritime conditions. After transforming range-time profiles of the data, a method was developed in Radon space to easily distinguish between the normative form of the sea clutter and the anomalous forms of the targets, after which the normative form is reduced. The proposed processing technique shows consistent improvements of 10-12 dB in the signal-to-clutter ratio.
