Through the analysis of the test data and the new development in the relevant literature , some more realistic models for sea - clutter and multipath propagation is concluded and the simulation is accomplished in the software . they provide the foundation for low - altitude radar target detection & tracking techniques research . in the second part , radar low - altitude target detection & parameters ( elevation - azimuth - range delay - doppler shift ) measure are studied (海)雜波和目標(biāo)信號(hào)的多徑傳播嚴(yán)重影響了雷達(dá)低空目標(biāo)探測與跟蹤的性能,通過分析國內(nèi)外的有關(guān)試驗(yàn)數(shù)據(jù)和最新的研究進(jìn)展,總結(jié)出比較接近實(shí)際的海雜波和多徑傳播模型,并在有關(guān)軟件中實(shí)現(xiàn)了海雜波與多徑傳播的仿真,為進(jìn)一步研究各種低空目標(biāo)探測與跟蹤測量算法提供了保證。
