De-Interleaving and Identification of Pulsed Radar Signals Using ESM Receiver System

An ESM sensor composed of either a single channel or multi channel superhetrodyne receiver followed by Digital receiver and ELINT processor to identify radar emitters in a particular frequency band of interest. In real life, such systems may encounter with a continuous stream of pulses accompanied by many imperfections, and it should work on real-time basis. In order to handle such circumstances and to develop better De-interleaving algorithms, a simulation environment is needed. In this project the design of a scenario-based mixed pulse generator (simulator) and De-interleaving of various pulse characteristics of radar such Stagger PRI, Jitter PRI, Sliding PRI, Dwell and switch PRIs. During this project the algorithms are implemented in Matlab environment and implementation of hardware in Xilinx FPGA using ISE environment. Apart from this the commands to front end system is implemented in Ethernet interface and interleaved pulse data is received in through fibre optic interface.
