Lfmcw radar adopts the receiver with the structure of “ homodyne - fourier ”, and acquires the range spectrum after its if signal is sampled, and then processed by ftt
Lfmcw雷達採用了「差拍-傅立葉」接收機結構，其回波中頻信號經數字採集后進行fft處理，從而獲得雷達的距離譜。It is composed of thirteen functin ? components including two 3 - db y - junction power splitter, two directional couplers, two waveguide attenuators and one polarizer of waveguide itself. the prominent feature of the device is that it has a beat detection function with respect to the single y - branch mioc device, and it plays an important role in improving the inertial - grade and the high precision steady - aim system because of the beat detection function. farthermore it has direct influence on the improvement of the high flexibility, shockproof and overload - resistance for the steady - aim system
器件的工作波長為1 . 3 m ，集分束器、合束器、起偏器/檢偏器、相位調制器、波導吸收器等十三個功能單元於一體，除了單y多功能集成光路器件具備的功能外，它還具有拍頻檢測功能，因而對提高慣導級和高精度穩瞄系統起著重要的作用，並直接影響著穩瞄系統的高機動性、抗沖擊力和過載能力的提高。
