Abstract
Aimed at the problem of adaptive detection threshold in the digital channelized receiver, this paper introduces a threshold generating method based on sorting statistics, which utilizes the magnitude vector in small serial number after ranking output amplitude of sub-channels from small to large order as a noise sample to form the threshold, but sorting operation of this method takes up a large number of FPGA resources. When intercepting and receiving the sky signal, this paper puts forward a simplified and improved method based on characteristics of clean sky signal environment and pulse signal environment. The sliding adaptive threshold method takes the forepart signal of the same channel as a noise sample to form the threshold.
