low-altitude detection 中文意思是什麼
low-altitude detection
解釋
低空探測-
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。 -
Thirdly, this dissertation analyses the echo simulation of chirp - subpulse stepped frequency signal and chirp signal. and the detection capability of chirp - subpulse stepped frequency signal and chirp signal in low altitude moving target is compared. the results show that chirp - subpulse stepped frequency is better
再次，本文分析了chirp子脈沖頻率步進信號和chirp信號的回波模擬問題，在此基礎上，對chirp子脈沖頻率步進信號和chirp信號對低空動目標檢測的性能進行了比較，結果顯示chirp子脈沖頻率步進信號具有較好的性能。 -
