radar patrol line 中文意思是什麼
radar patrol line
解釋
雷達巡邏線-
Different from detecting space of land - based radar which has relative unchangabledetection space, aew radar ’ s detecting space changes with the carrier ' s patrol line. what ’ smore, because of both movements of carrier and targets, aew radar will detect targets whichwere out of its coverage
地基雷達的探測空間是相對固定的,而機載預警雷達的探測范圍隨載機航線的變化而變化;由於載機和目標同時都在運動,使得某一時刻在載機探測范圍之外的目標也可能在後來的飛行過程中被探測到。 -
( 2 ) if not considering blind space and targets are uniformly distributed, detectionperformance are close for the three kinds of line when speed - ratio is less than 1, and cross - toline will achieve higher enter - cover - probability when speed - ratio is more than 1. if takingblind space into account, for case of balance - beam radar, cross - away line can get higherstrict - enter - cover - probability. but for fear that probablely - enter - cover target distribution comesbehind the patrol line, the three factors should be limited if taking cross line
若考慮盲區的影響,對平衡木構型的雷達而言,交叉同向航線的嚴格覆蓋率較大;但為了使區域縱深不反向至我方空域,採用交叉航線時航線橫比、航線縱比、速度比的取值范圍要受到限制,否則雷達動態性能將大打折扣。
