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。Detecting sonar pulse transmitted by active sonar, it is called " sonar pulse detection ". the main task of it is to measure the working parameter of active sonar and track the target
聲吶脈沖偵察的主要任務是偵察目標主動聲吶的工作參數，對目標實施跟蹤，是利用目標主動聲吶發射的脈沖信號來探測目標的被動測距技術。Measuring the parameters of pulse with high speed and precision is the base of electronic reconnaissance
