aspect n. 1.樣子,光景;容貌,神色。 2.(房屋等的)方向,方位。 3.局勢,形勢,局面。 4.(問題的)方面;見地。 5.【語法】體,態(tài)。 a beautiful aspect 好景;美觀。 a thing in its true aspect 事物的真相。 The house has a southern aspect. 那間房子朝南。 the physical aspect of China 中國的地勢。 consider a question in all its aspects 由各方面考慮問題。 assume [take on] a new aspect 面目一新,呈新局面。
Firstly , with the consideration of the frequency and aspect angle dependent parameters of the low frequency uwb - sar , the radar equation for calibration is proposed 首先充分考慮了系統(tǒng)參量的頻率和方位角特性,提出了適合低頻uwb - sar校準的雷達方程。
Additionally , target detection will take into account a target ' s radar cross section ( rcs ) , its aspect angle , and its air speed ( targets below the threshold gate will not be detected ) 外加目標的確定怎加了計算目標的rcs值當空速低于這個門限的時候目標將無法被察覺
This method can save the space of memory and reduce the computation time . because only the parameters of scattering centers are stored and genetic algorithm is used to search for aspect angle , the method is very suitable for the employment in real - time and restrictive environment . in chapter 3 , the architecture of mmw seeker is studied 該方法以目標多散射中心理論為基礎,只需要存貯目標的三維散射模型參數(shù),需要的存貯量較少;與常規(guī)的全姿態(tài)角匹配識別方法比較,基于目標散射模型的匹配識別方法,由于利用了遺傳算法的全局尋優(yōu)能力,計算量較小。
Evenly , to the economic benefits , they have destroyed tourist resources and their environment . so the tourist academe should make a breach in the study of problem of tourist environment , a system of theory and means which is effective in practices . on the base of study practices and investigates outdoors , this paper puts forward a signify idea of tourist resource environment management , and design a system of nature landscape tourist resources environment , which is full , systematic and material , including a system of ideas and a system of means , to try hard to seek a new aspect angle for the tourist academe 本文在科研實踐和野外調查的基礎上,從自然風景區(qū)旅游資源(生境)的理論認識出發(fā),提出旅游資源環(huán)境管理的重要思想,并從理念體系到方法體系構建出一個完整的系統(tǒng)的邏輯遞進的又具體可行的旅游資源環(huán)境管理體系,力圖為自然風景區(qū)管理者提供一個在理論上有指導意義和方法上可參照實施的模板,并為學術界提出一個新視角。
The three kinds of simulated point targets are designed and the rangeprofiles at aspect angle are computed . the radar target recognition method based on the optimal cluster centers is simulated and studied . it is discovered that the algorithm is effective when there are lots of training data , but noneffective when there are only a few training data 2 、對最優(yōu)聚類中心目標識別法進行仿真實驗并研究其識別性能,實驗結果表明該算法在大樣本訓練數(shù)據(jù)時能得到較高識別率,是一種有效、可行的識別算法,但在少樣本訓練數(shù)據(jù)時,所得識別率急劇下降。
