Surface Ship Target Classification Using H.F. Multi-Frequency Radar.
Abstract
A number of studies leading to the development of ship target identification from the return from High Frequency Over the Horizon (HF OTH) radar returns were implemented. All of the studies used data from an available data base where measurements were made of scale models on a ground plane. The frequencies used were consistent with the HF band (2-25 MHz in this case). The work reported on here is the initial phase of the research, and the data base was not directly usable for the testing of specific algorithms for the identification of surface ships in general. The data base was used instead to test the general identifiability of surface ships using HF OTH radar returns. Nearest neighbor techniques and hyperline techniques were used to measure the clustering and the separation of the amplitude and phase data from the ship models in hyperspace (i.e., parameter space). Ramp response curves and pole extraction techniques were used to indicate the source of the reliability of the features found in the target return data. It was shown that the OTH returns can be expected to be inherently useful for the identification of ships. (Author)
