In telecommunications, the term “loop gain” can refer to the total usable power gain of a carrier terminal or two-wire repeater . The maximum usable gain is determined by, and may not exceed, the losses in the closed path.
Read moreWhat is Sigma in radar?
Pt = Transmit Power. fo = Transmit Frequency. Lamda = Transmit Wavelength. G = Antenna Gain. Sigma = Radar Cross Section .
Read moreWhat is radar range definition?
Range, or distance, is determined by measuring the total time it takes for the radar signal to make the round trip to the target and back (see below). The angular direction of a target is found from the direction in which the antenna points at the time the echo signal is received.
Read moreWhy is there a max range for radar?
Maximum Range: Radar Max Range is determined, ideally speaking, on the properties of the antenna only. A signal at a certain frequency is transmitted, reflected, then hopefully, detected. Due to the three-dimensional propagation of radar waves, frequency hold the highest weight in determining range .
Read moreWhat is the minimum range of radar?
The pulse width (H) determines the minimum range at which targets can be detected. This minimum range is approximately ½ the length of the wave burst . In the case of the 4.5µS pulse, the minimum range would be 675 meters (2,215 feet).
Read moreWhat is maximum unambiguous range in radar?
The unambiguous range of a radar is the maximum range at which a target can be located so as to guarantee that the reflected signal/pulse from that target corresponds to the most recent transmitted pulse .
Read moreHow far can radar measure?
Radio waves travel at the speed of light, roughly 1,000 feet per microsecond , so if the radar set has a good high-speed clock it can measure the distance of the airplane very accurately.
