A Joint Tactical Information Distribution System Signal Detection Method Based on Multi-level Channelization and Channel Selection

In order to detect the signals of the Joint Tactical Information Distribution System (JTIDS), a efficient multi-level channelization processing method was designed based on the existing channelized reception. By dividing the channels in the channelization model into two levels, the requirement of frequency interval of JTIDS signals was met, and the computational complexity was reduced. When performing threshold detection, the channel selection algorithm based on peak detection solved the channel ambiguity problem caused by narrowband division in the channelized reception process, and improved the accuracy of detection results.
