What is a pulse radar?
Pulse Radar is a well -known method of detecting objects by publishing short impulses of radar energy into space and then by detecting energy that reflects back after the object is hit. In order to determine the distance of the object, the radar system measures the time during which the pulse goes to and from the object. Pulse radar has important functions in air traffic, detection of naval and military objects, supervision of weather weather and space exploration, among other things. Robert Morris invented in 1943. The monopulse radar was used moderately due to its costly maintenance and was used only in special cases, for example in monitoring the Nike Ajax and Apollo, Gemini and Mercury Space Explorations. Since then, it has become the basis for all subsequent radar technologies.
Pulse radar system has two types. The first type is a simple pulse radar that sends one energy pulse at a time. After the pulse is reflected back, the radar transmits another energy pulse. This process determines the distanceThe object and can estimate the speed it travels, although the estimate is not high.
The second type is the radar pulse-doppler. This species is more sophisticated because it works on the principle of Doppler's shift, which states that the object changes its wave frequency as it moves towards the observer and apart. The Puls-Doppler radar is released by a permanent stream of radar pulses. Analysis of several pulses, unlike one, causes more accurate reading of the speed of the object. This capacity makes more effective detection of moving objects between stationary, unlike a pulse radar, which is more useful for the simply identification of the object.
Pulse radar systems, whether using pulse radar or pulse-doppler radar, need four main parts to work: transmitter, antenna, receiver and interface. The transmitter is responsible for broadcasting the energy of the radio. The antenna is the main recipient back after the energy mirroring. ATAround the receiver is to enlarge the signal that the antenna receives, and the interface provides the setting switch and visual display for the entire process.
