Evaluation of the FMICW Waveform in HF Surface Radar Applications

摘要

The operation and performance of the Frequency Modulated Interrupted ContinuousWave (FMICW) waveform in ship and aircraft detection using high frequency surface wave radar are analyzed. A modified processing scheme for the FMICW waveform which circumvents the problem of ambiguous range response is presented. The increase in hardware complexity for the modified processing scheme is moderate. Two measures: the signal-to-clutter ratio and the signal-to-noise ratio are used to evaluate the performance of the FMICW. It is concluded that the FMICW is superior to the simple pulsed waveform in ship-detection application. For aircraft detection, the advantage of the FMICW is marginal. Parameters optimized for ship-detection application will not be optimal for aircraft-detection
