Abstract: Like most radars, Doppler radar detects an object by sending out a series of pulses of electromagnetic radiation in the radio or microwave region of the spectrum. In this research, Doppler radar is used to find out the time period of a moving pendulum for different lengths, to measure the rotation rate in rpm, to determine the Doppler frequency of moving object and to know the less vibration measurement. This radar contains parabolic reflector and Monolithic Microwave ICs (MMICs) transceiver. Observation and measurements are taken from zelscope software. This software extracts the information of amplitude, time, frequency, FFT etc and this information can be used to device various configurations of the radar.
