Abstract


Tracking Receiver is an important component of the microwave remote sensing satellite receiving system。With the rapid development of remote sensing technique and the continuous improvement of image resolution, remote sensing data rate of LEO satellites is rising too。It is changing from ten trillion to more than 300 trillion。It requires higher G/T value narrower Beams、wider receiving channel and higher tracking precision of the receiving system to process high-rate remote-sensing image signal。In this paper, we discuss the design and implementation of a high-performance dual-frequency differential-mode single-Monopulse tracking receiver。We use broadband frequency conversion technology to process the image signal of the remote sensing satellites and dual-frequency differential-mode single-monopulse tracking technology to track the satellites accurately。In this paper we firstly introduce the principle of monopulse tracking receiver and its typical forms, then discuss its implementation, thirdly give the design of each hardware module and software, complete the engineering calculation of the receiver, discuss some key technical problems, finally summarize the status of engineering applications。It shows that this receiver fully meets the needs of processing the high-rate signal of the microwave remote sensing satellites.
