Abstract:
Geostationary meteorological satellites are an important means for monitoring the land surface, atmosphere, ocean, and space environment, widely used in meteorological, agricultural, space, and environmental fields，providing a large amount of scientific data for researchers The design and implementation of the FY2 receiver are described，mainly including the secondary frequency conversion method, digital demodulation based on HSP50110/HSP50210, differential decoding, signal indicating, key parameter settings, and so on Taking the bit error rate as direct indicator for evaluating the performance of the receiver， in combination with the images, a performance evaluation of the receiver is conducted, and the results show that the designed receiver has a low error rate, and provides satisfactory images.
