Abstract
Frequency-modulated continuous wave radar is generally used for calculating range and speed of any target. A research paper is intended to develop back-end electronics for frequency-modulated continuous wave (FMCW) radar with optimum usage of field-programmable gate array (FPGA)-based processing unit. Sampling of the received IQ (in-phase and quadrature-phase) signals is done at speed of 500 KSPS using 12-bit ADC128S102. Acquired data is further stored into internal memory of FPGA for post-processing. Zero-crossing algorithm is implemented on the received signal to obtain the beat frequency of the same. Moreover, stored data and processed data are transferred to the computer using SPI protocol. LabVIEW-based simulator is also developed to process the received data and retrieve the beat frequency from it.
