  1. 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）雜波和目標信號的多徑傳播嚴重影響了雷達低空目標探測與跟蹤的性能，通過分析國內外的有關試驗數據和最新的研究進展，總結出比較接近實際的海雜波和多徑傳播模型，並在有關軟體中實現了海雜波與多徑傳播的模擬，為進一步研究各種低空目標探測與跟蹤測量演算法提供了保證。
  2. Several topics on coding and modulation theories of uav communication were discussed in this thesis. by analyzing features of uav communication, difference on three aspect between uav and satellite / civil mobile communication were pointed out, i. e. rapidity of the channel state parameters changing when low - altitude flying, wide range of the signal to noise ratio ( snr ) in receiver, and demand on transmission delay

    無人機通信與衛星通信、移動通信有相似之處，也有明顯不同，主要是：無人機低空飛行時通道參數變化劇烈，通信中接收機信噪比變化范圍大，要求傳輸時延短。
