Signal processing of position plan indicator display for weather radar

This paper presents signal processing of position plan indicator (PPI) display for weather radar. The radar uses technique of frequency-modulated continuous-wave (FMC) to monitor the precipitation events in atmosphere and climate investigation. The use of FMCW technique is chosen in order to reduce the power at transmitter. For time efficiency, real-time domain processing conducted using Matlab® is implemented to process the received signal. Meanwhile, the PPI display is employed in the system due to its ability to map the area covered by the radar beam.
