( 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。 -
This paper first analyzes the characteristics on train working diagram of urban rail transit, on the basis of describing property on rail line of urban rail transit, this paper puts forward theory of two stations drawing and three stations drawing which taking the setting of vehicle depots as the core of the subject designs sequence and contrary advance calculating methods to calculate the train arrival and departure time at mediate station, and builds mathematic model on the train working diagram of urban rail transit taking same interval time of train traveling as the target function
摘要在對城市軌道交通線路屬性進行數學描述的基礎上，以車輛段設置地點為核心，提出兩站圖及三站圖理論，設計分層順序和反序推點演算法計算列車在中間站的到發時刻，並以分時段列車等間隔運行為目標函數，構建城市軌道交通列車運行圖通用數學模型。
