What is pulsed radar used for?
Applications. Pulse radars are designed mainly for long distances. The main application is still the military area. Other applications include air traffic control, weather observation (especially precipitation radar) as well as the satellite-based remote sensing of the earth’s surface.
What does pulse mean on a radar?
The amount of power transmitted by a radar during a given pulse. Note that because these pulses are widely spaced, the average power will be much smaller. Pulse. A short burst of electromagnetic energy that a radar sends out in a straight line to detect a precipitation target.
How does a pulsed radar work?
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. This gives pulse-Doppler radars “look-down/shoot-down” capability.
What does the radar receiver detect and measure?
The term “radar” is an abbreviation for RAdio Detection And Ranging; it is a system for detecting objects using reflected electromagnetic energy. Radar systems can measure the direction, altitude, range, and speed of distant objects far from the radar site.
What is receiver exciter?
The Collins Aerospace RT-2200 Receiver-Exciter is your multipurpose solution. Use it as a receiver, an exciter or both in single-site or split-site installations. With it, you get conventional reception and transmission of voice and digital data messages in the 1.5 to 29.99999 MHz frequency range.
What is minimum range and pulse length?
Monostatic pulse radar sets use the same antenna for transmitting and receiving. A typical value of 1 µs pulse width of a short range radar corresponds to a minimum range of about 150 m, which is generally acceptable. …
How fast is a radar pulse?
roughly 300,000 km per second
Some radar pulse widths are even of nanosecond (10−9 second) duration. Radar waves travel through the atmosphere at roughly 300,000 km per second (the speed of light). The range to a target is determined by measuring the time that a radar signal takes to travel out to the target and back.
What is blind speed?
The blind speed is a radial speed of the airplane at which the phase shifting of the echo-signal has the value ±n · 360° between two pulse periods. With blind speeds moving targets are suppressed by a MTI system like ground clutters.
