A Real-time Software Defined Radar Index Analysis Prototype System

The real-time and comprehensive nature of radar signal processing and index analysis is of great significance to the index test of a radar system. Based on the flexible and open characteristics of software definition technology, a novel radar real-time indicator analysis system is developed in this paper. Using a socket network communication architecture based on the UDP protocol, the software can meet the real-time requirements, so that the synchronization of radar signal acquisition and analysis can be guaranteed. In addition, due to the modular design, signal processing, indicator analysis, and other functions are available in this software. Specifically, the software can not only intuitively display the signal waveform, but also give the indicator analysis results of the time domain, frequency domain, and other modulation domains, which meets the requirements of comprehensive analysis. The test results show that the software can greatly improve the efficiency of radar signal index analysis by synchronizing of data acquisition and analysis, and thereby has broad applicability in an actual radar signal processing environment.
