What is a wave gate in a measurement radar? What do you mean by distance gate and tracking gate?

In the measurement radar, "wave gate" refers to a time window set when the radar receives the signal, which is used to control the time when the radar system receives the echo signal. It can reduce interference and improve the recognition and tracking ability of radar system.

"Distance Gate" is a function of radar system, which can limit the maximum distance of radar receiving objects. This kind of wave gate is usually realized by controlling the time delay of radar receiving echo.

"Tracking Gate" is a kind of gate used to track the target and get more information after the target is detected. Generally, it can be operated within the scope of the gate.
