A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object’s velocity .
Read moreWhat is pulse of radar?
The pulse length is usually called the PULSE WIDTH in radar systems. The pulse interval, or the time from the beginning of one pulse to the beginning of the next, is determined by the number of pulses which are transmitted in a given period of time . In radar, we measure all time in seconds (or fractions of seconds).
Read moreIs the Doppler effect the same as Doppler radar?
The Doppler effect shifts the received frequency up or down based on the radial velocity of target (closing or opening) in the beam, allowing for the direct and highly accurate measurement of target velocity. A Doppler radar is a radar that produces a velocity measurement as one of its outputs .
Read moreHow many antenna are used in CW Doppler radar?
The receiver uses two antennas – one antenna aimed at the target and one antenna aimed at the transmit antenna.
Read moreHow does a Doppler radar work?
Doppler radar works by sending a beam of electromagnetic radiation waves from the transmitter (TX Antenna), with a precise frequency, at a moving object . Once the electromagnetic radiation wave comes in contact with an object, it travels back towards the receiver (RX Antenna).12 Haz 2020
Read moreWhat is antenna in radar system?
The radar antenna transmits pulses of radio waves which bounce off any object in their path . The object returns a small part of the wave’s energy to the receiver antenna which is usually located at the same site as the transmitter. The basic use of the traffic radars is the measurement of the speed of the vehicle.

Among the different types of reflector Antennas, the simple parabolic reflectors and the Cassegrain feed parabolic reflectors are the most commonly used ones.
