Real time threat radar parameter extraction in electronic support systems

Extraction of the radar signal parameters is one of the most important and fundamental tasks for the electronic support systems. Analysing of these parameters in electronic warfare systems is significant for recognizing and classifying of the characteristics of the threat radar emitters. The parameter list is called as pulse descriptive word (PDW) and these can be sorted mainly as time of arrival (TOA), pulse width (PW), pulse amplitude (PA), frequency (RF) and angle of arrival (AOA). In electronic warfare systems, radar warning receiver (RWR) and electronic support measures (ESM) systems are needed in order to perform electronic counter measures (ECM) techniques. PDW of thethreat radars must be found by processing the signals that are received by the antennas in the parameter extractor module so that these techniques can be executed in realtime. In this thesis, basic PDW parameters are extracted in real time and compared for different analysis scenarios on FPGA. The results are given with error analysis.
