moreover, theory of the random pulse position modulation and random binary phase-coded ( rppm & rbpc ) pulse doppler is also discussed 在此基礎(chǔ)上,進一步討論了隨機脈位調(diào)制加隨機二相碼調(diào)相脈沖多普勒雷達原理。
random pulse position modulation ( rppm ) signal not only has good resolution of distance and velocity, but also has low probability of interception and strong properties of eccm 隨機脈位調(diào)制信號不僅具有良好的距離和速度分辨力,而且具有較低的被截獲概率和較高的抗干擾性能。
random pulse width modulation ( rpwm ) techniques for voltage-controlled power electronic converters have been attracting an increased interest due to the unique effects of these techniques on the converter-supplied drive systems 作為交流傳動系統(tǒng)中的一項關(guān)鍵技術(shù),pwm(pulsewidthmodulation)技術(shù)在提高效率、降低能耗、減少污染等方面具有重大意義。
