Implementation of mechanical scanning and signal processing for FMCW radar

Scanning antenna in the radar are added to estimate the position of the object. On surveillance radar, the scanning movements is carried out due to detection angular position of the object. Using Arduino™ and DC motor we could steer the beam of antenna mechanically. It will provide the information of angular position which will be sent through RS-232 serial port. Received beat signals of Frequency Modulated Continuous Wave (FMCW) radar is used to estimate the object range. Azimuth and distance will be plot to an Plan Position Indicator (PPI)-Display. Realtime performance of standar FMCW radar data processing procedures and radar data visualization is achieved by utilizing the standard jack audio and advance graphical processor.
