Özet:

 

This paper describes the development of the SeaSonde High  Frequency Radar system into a dual-use application for the mapping of  ocean surface currents and detection of ships at sea.  This  development entailed the creation of a new radar waveform that would  permit this dual-use as well as a detection algorithm to identify the  ships in the radar spectra.  The detection algorithm utilizes two  methods for calculating a background signal level: an infinite impulse  response (IIR) filter and a two-dimensional median filter.  These two  methods are employed simultaneously with multiple length averaging  times to maximize the number of detections.  The initial phase of  development focused on improving the radar waveform to maximize the  results for ship detection while still retaining the ability to  measure surface currents.  The latter phase of the development  concentrated on testing the detection algorithm on a known vessel in  different environmental conditions.
