Abstract
In this project, a generic of the radar transponder response was designed on FPGA. The design on the transmitting pulse p1,p2 and p3,Pulse detection and mode generation and Transponder with delays are user configurable through a graphical user interface(GUI).The radar transponder response based on the secondary surveillance radar. It is designed for real time application using vector signal transceiver (VST). RTR are an essential requirement in the defense industry for Electronic Counter Measure (ECM) and performance evaluation of radars without the need of expensive trips and interference from commercial wireless devices. The current design is capable of Transmission of pulse P1,P2 and P3, and delay calculation and mode selection, Range detection in real time and operates based on the principle of Digital Radio Frequency Memory (DRFM), which presents a reliable method for storing the Radio Frequency (RF) signal in digital format. Before regenerating the stored waveform for transmission, of the pulse P1,P2 and P3and mode selection & Range of the target being presented to RUT are incorporated into the waveform through vector data modifications & corresponding delay respectively. Multiple targets are simulated through cascading the hardware with synchronization of their local oscillators. The algorithm to perform the required signal processing is designed specifically for VST using the FPGA module of National Instrument’s LabVIEW software, and tested on the same.
