Abstract：At present, the component performance is the main limiting factor of realizing ideal
software radio, with the development of microelectronics technology and large-scale integrated circuit, practical software radio is marching gradually towards idealization. This article introduced the structure and the characteristic of the digital receiver ICS554. Giving its application example in the software high frequency radar system, including the system hardware schematic diagram, the digital receiver module software design concept and the work flow chart. And has tested its performance, the actual result indicated that this digital receiver works stably, its performance is good, at present it has already applied in the software high frequency radar system.
