Frequencydiversity tolow-angledetecting usinga highly deterministic multipath signalmodel

In thispaper,basedon a highlydeterministic multipath signal model, wederives 4-rays echosignal formula inmultipath. UseMTD todetect thelow-angle movingtarget, butitsperformance islimited bythemultipath propagation factor. Frequency diversity methodcanresist themultipath fading. Simultaneous detecting inmultiple diversity channels canimprove thelow-angle detecting performance. Andthis paperputsforward multiple diversity channel accumulation algorithm toadvancethedetecting performance toa higher position. Simulation shownthis technique iseffective.
