This paper presents the design of an IF (Intermediate Frequency) signal receptor in order to modernize the one included on the Vitro RIR-778C tracking radar.The radar’s technique for doing the object tracking is the one called monopulse, therefore this new system has to process the signals according to this method.For a proper signal processing, the IF analog signals are converted to a digital form by undersampling them.The physical device chosen for accomplish this is an FPGA programmed by a hardware description language.Despite the fact that it wasn’t possible to perform real tests in the radar’s environment, final results are promising, being very similar to those who’d been simulated.
