bandwidth product
解釋
帶寬生成-
Pulse compression technique is widely used in modern radar systems. it solves the contradiction between the range and velocity resolution. large time - bandwidth product signals such as linear frequency modulation signals ( lfm ) are used in pulse compression technique to improve the resolution in range domain
現代雷達系統廣泛採用脈沖壓縮技術，在確保雷達作用距離和速度分辨力的前提下，採用大時帶積脈沖壓縮信號:如線性調頻（ lfm ）信號提高距離分辨力。 -
Space - bandwidth product
空間帶寬積 -
The joint transform correlator ( jtc ) is paid more attention by researchers than the matched filtering correlator ( mfc ) with its advantages, such as high spatial bandwidth product, without integrated filtering and real - time operation etc. photorefractive crystals have some advantages, such as fast response, high spatial resolution and large storage capacity etc. we can exert both advantages by combining the photorefractive crystal with the jtc
與匹配濾波相關器相比，聯合變換相關器具有諸多優點，如空間帶寬積高、無需濾波綜合、易於實時操作等，所以近年來更加引起人們的研究興趣。光折變晶體具有響應速度快、空間解析度高、存儲容量大等優點。將光折變晶體與聯合變換相關器相結合構成光折變聯合變換相關器，就可以充分發揮二者的優勢。 -
Based on the acoustic energy flow detection, the spatial energy flow suppression can obtain time - space gain in direct proportion to time - bandwidth product, which is just the main advantage of the vector transducer
基於矢量水聽器的聲能流檢測器利用空間聲能流抵消技術相對于聲壓檢測器可獲得與時間帶寬積成正比的時空增益。 -
A new if simulation signal digital model was developed, which has the ability to simulate the ocean return wave noise and the instrument thermal noise. by this simulation data, smle is successfully tested, and the rf ocean return wave simulator also worked correctly. it is difficult for altimeter to realize closed loop internal calibration with a large time - bandwidth product
（ 4 ）提出了雷達高度計海面回波中頻模擬信號的數字模型，該模型具有模擬高度計海面回波噪聲和儀器熱噪聲的功能；基於該模型的軟體模擬器成功的對高度計跟蹤器進行了驗證；同時，該模型模擬的信號應用於雷達高度計射頻回波模擬器也獲得了成功。 -
Fsk / psk radar signal is the signal with both fsk and psk modulation at one time. it is with large bandwidth time product ( bt ), thumbtack - like ambiguity function and well ability of anti - emi. the fsk / psk signals of which the frequency - hopping and bi - phase sequences were randomly chosen often have high sidelobe level
Fsk / psk信號是同時進行頻移鍵控（ fsk ）和相移鍵控（ psk ）調制的信號，該信號具有大時帶寬積（ bt ）和高分辨特性，並具有「圖釘型」模糊圖結構、低截獲概率（ lpi ）特性和較好的抗干擾能力，受到了廣泛的重視。 -
