operation of a simple pulse radar system. B. The student will know the following terms: pulse width, pulse repetition frequency, carrier frequency, peak power, average power, and duty cycle. C. The student will know the block diagram of a simple pulse radar system and will comprehend the major components of that system.The pulse repetition frequency (PRF) is the number of pulses of a repeating signal in a specific time unit, normally measured in pulses per second. The term is used within a number of technical disciplines, notably radar. pulse repetition frequency radar system

18. 7 Pulse Repetition Frequency A high pulse repetition frequency (PRF) has several advantages. First, the higher the PRF, the greater the average power the radar is transmitting (assuming the peak power of each pulse is limited by the transmit circuitry), and the better the chance of detection of targets.

A radar pulse train is a type of amplitude modulation of the radar frequency. carrier wave, similar to how carrier waves are modulated in communication systems. In this case, the information signal is quite simple: a single pulse repeated at. regular intervals. Pulse repetition frequency (PRF) A radar with a 1 horizontal beamwidth that sweeps the entire 360 horizon every 2 seconds with a PRF of 1080 Hz will radiate 6 pulses over each 1degree arc. If the receiver needs at least 12 reflected pulses of similar amplitudes pulse repetition frequency radar system Pulse repetition frequency. In radar, a radio signal of a particular carrier frequency is turned on and off; the term frequency refers to the carrier, while the PRF refers to the number of switches. Both are measured in terms of cycle per second, or hertz. The PRF is normally much lower than the frequency.

Pulse Repetition Frequency Radar signals should be transmitted at every clock pulse. The duration between the two clock pulses should be properly chosen in such a way that the echo signal corresponding to present clock pulse should be received before the next clock pulse. pulse repetition frequency radar system The Pulse Repetition Frequency (PRF) of the radar system is the number of pulses that are transmitted per second. Radar systems radiate each pulse at the carrier frequency during transmit time (or Pulse Width PW), wait for returning echoes during listening or rest time, and then radiate the next pulse, as shown in the figure. A high pulse repetition frequency pulse doppler radar in which the prf is large enough to have no blind speeds [as given by Eq. (32) within the expected values of target doppler frequencies. A pulseDoppler radar is a radar system that determines the range to a target using pulsetiming techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuouswave radars, which were formerly separate due to the complexity of the electronics.
