在通視情況使得其它儀器都無法應用的季節內,可用微波測距儀測量。The principle 、 configuration and characteristics of the measure and control system in the grinding circuit with hydrocyclone classifier are introduced. the function and application result of the measure and control system are discussed with practical application
本文介紹了井下進行采區控制導線的測量時,在前、后視點懸掛棱鏡進行光電測距的方法及應用情況。The use of interferometer to detect and analyze laser radiation is well known, but when the intense ratio of the laser radiation to the background natural light radiation is too small, the laser radiation cannot be detected. a novel more sensitive method for detect of wideband weak incident laser in strong background noise is introduced in this paper. the optical unit uses two wedge interferometers and two line array detectors. the incoming light radiation is divided into two beams and through the interferometers
在被動激光偵察告警中,對微弱脈沖激光信號的探測是一個難點。當探測距離相當遠或視場內接收的背景光輻射很強時,脈沖激光信號到達探測器的能量很小,會淹沒在強大的背景光信號中而探測不到。本論文提出了一種探測微弱脈沖激光信號的方法,可對強烈背景光中的激光威脅信號進行探測和告警,並給出其波長參數。The stadia method can be used for measuring distances by standard surveying techniques.
採用視距法定位可按一般陸地測量方法進行。The binocular stereo ranging method based on the principle of triangle measuring is an important method which can do three - dimension ( 3 - d ) measurement and acquire the information of 3 - d surface profile
基於三角測量原理的立體視差測距方法是進行三維測量,獲取三維場景距離信息的重要方法。It can construct a reference path with lowest danger for the uav ( unmanned aerial vehicle ) by accounting for some aircraft performance characteristics, the mission goals, the threat information and the terrain information. this paper puts emphasis on the study of path planning algorithms and the analysis of uav missions. the main contributions are summarized as follows : ( 1 ) the threat environment, mainly as the radar threat, is studied and the detection probability of the aircraft is analyzed
本論文主要根據無人機的作戰任務方式進行了航路規劃研究,包括攻擊航路和偵察監視任務航路,具體內容包括以下幾個方面: ( 1 )本論文分析了威脅空間的威脅計算問題,對飛行器探測概率進行定量化的研究,根據恆虛警處理技術對雷達探測概率計算方法進行了總結,說明了計算單部雷達探測概率問題的方法,在此基礎上對雷達網的探測概率計算進行了討論,提出了相對于距離的探測概率求解方法和思路,用於攻擊航路規劃中的威脅計算。To measure the distance of heavenly objects close to us, we can use a method called " parallax ", a simple visual phenomenon that was well understood by ancient greek more than two thousand years ago and was then used to estimate the earth s radius
要量度鄰近天體的距離,我們可採用視差法parallax 。古希臘天文學家在二千多年前已提出視差法的基本原理,並藉此測定地球的半徑。In cellular envirorunents, because of the influence of several adverse factors, such as muitipath, non - line - of sight propagation, noise, interference and channel frequency characteristics, radio statistics measuremenis like tdoa, toa and aoa related to mobile position, the performance of location algorithms mny be significantly degraded and the position estimation of ms is inevitably biased
在蜂窩網路環境中,由於受多徑、非視距傳播、噪聲、干擾和通道頻率特性等多種不利因素的綜合影響,使tdoa 、 toa 、 aoa等與移動臺位置有關的電波特徵測量值不可避免地出現較大誤差,從而使各種定位演算法的性能顯著下降,造成移動臺位置估計出現較大偏差。At first, by using the feature that the excess delays of nlos propagation follow the exponential distribution, the los propagation parameters are reconstructed and the toa parameters measured from all bs are preprocessed. then, the ms ' s position is estimated by the los locating algorithm with the preprocessed data. finally, to mitigate the effect of the errors in reconstructed parameters, the estimated results are smoothed
首先,利用非視距傳播時延服從指數分佈的特點,對不同基站一次測量的數據進行預處理,重構視距傳輸參量;然後,對處理后的數據採用視距定位演算法估計移動臺位置;最後,對估計結果進行平滑后處理,以減小重構出的參量誤差的影響,進一步提高定位精度。分享友人
