脈寬鑒別 的英文怎麼說
中文拼音 [màikuānjiànbié]
脈寬鑒別
英文
pulse duration discrimination-
Pulse width discriminator
脈沖寬度鑒別器In order to improve the ranging accuracy of a lidar, the effect of amplitude and width of the echo signal on the ranging accuracy of a lidar with bell - type laser pulses in temporal domain and gaussian pulses in spatial domain, was studied under the condition of constant - voltage - amplitude discrimination
摘要為了提高脈沖激光雷達的測距精度,研究了光束在空域為高斯光束、時域為鐘型脈沖的激光雷達在恆電壓幅度鑒別模式下,回波信號幅度變化和寬度變化對測距精度的影響。First, delay window is used to reduce influence of pulse disturbance and signal amplitude to measurement result. second, according to the feature that width of receiving signal is wider than disturbing signal, width differentiation circuit is utilized to distinguish receiving signal and disturbing signal. third, most of digital circuits are integrated into isplsi ( in system programmable large scale integrated chip ) 1032 so as to simplify design and to develop the stability and reliability of the system
關于提高系統的穩定性和可靠性問題:一是採用了延遲窗口接收技術,以盡可能減小干擾脈沖對測量結果的影響;二是根據接收信號脈寬比干擾信號脈寬要寬的特點,採用脈寬鑒別電路來鑒別接收信號;三是用可編程大規模晶元isplsi1032對系統大部分的數字電路進行了集成化設計,達到既簡化電路設計、又提高系統穩定性可靠性的目的。
