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.
