摘要

This report describes a high-fidelity simulation of the received signals produced by a low pulse repetition frequency shipborne pulsed Doppler radar when observing a sea-skimming anti-ship missile moving through precipitation above the sea. The simulation was designed as a component of a larger simulation aimed at determining the detection performance of radar operating in clutter conditions. The modeled radar system uses a phased array antenna and has the ability to vary the parameters of the transmitted waveform from burst to burst. The output of the simulation is designed for combination with the output of clutter and signal processor simulations so that target detection in clutter can be examined. A complete description of the physical models used in the simulation and their mathematical implementation is presented. Example output data were used to derive propagation factor values, which were then compared with the output of the TERPEM commercial software package. Received power values also were derived from the example data and compared with the output of a multifunction radar simulator (ADAPT-MFR). Good agreement between the data sets was achieved, except for expected differences found at ranges near the radar horizon ('intermediate region'). The simulation is capable of producing realistic and useful signals for target detection studies, but it is recommended that it be integrated with the commercial software package TERPEM so that its applicability can be extended to any range near or beyond the radar horizon and to any atmospheric structure. Nevertheless, the favorable comparisons in the interference region demonstrate that this simulation is accurate, where applicable, and that it can be used with confidence for its stated purpose of assessing radar detection performance in clutter.
