What is FTC on radar?
Fast Time Constant (FTC) is a processing operation that can be applied to a radar video signal to remove low frequency components, for example due to weather effects. The FTC processing will filter these low frequency components, so that only pulses that rise and fall quickly will be displayed.
What is sensitivity time constant?
Sensitivity time control (STC), also known as swept-gain control, is a system used to attenuate the very strong signals returned from nearby ground clutter targets in the first few range gates of a radar receiver. For early radar systems, the solution was to point the signal away from the ground.
What is the use of the receiver unit features STC and FTC?
The STC and FTC are commonly used to some clutter. The radar signal is widely used for weather forecast, air port traffic control, military and fire control. The system implements radar processing procedures in real time mode in FPGA (field programmable gate array).
What is radar sensitivity?
The receiver sensitivity measurement determines the lowest possible power (MDS, Minimum Detectable Signal, or Minimum Discernible Signal) at the input of a receiver with which the radar can still detect a target. This measurement provides an important indication of the performance of a radar.
What is a radar sweep?
Radar Sweep View Controls. Overview. The Radar Sweep Controls are used to control displays of single level sweeps of radar data, and their display appears in the Main Display window.
What is the use of radar?
Radars are now used to help navigate ships in fog and airplanes in bad weather. Radar can detect a speeding car and track a satellite. Most importantly for meteorologists, radars can detect all sorts of atmospheric phenomena.
Why is a radar important?
Radars today are used to detect and track aircraft, spacecraft, and ships at sea as well as insects and birds in the atmosphere; measure the speed of automobiles; map the surface of the earth from space; and measure properties of the atmosphere and oceans.
