Pulse radar transceivers share an antenna. During the time of the transmitted pulse width τ, the receiver and the antenna feeder system are "disconnected", and the target echo cannot be received normally. After the transmitted pulse passes, the antenna transceiver switch returns to the receiving state, which also requires a period of time. Time t_0. During this time, it is difficult for the radar to measure the distance because it cannot receive the echo signal normally. Therefore, the minimum measurable distance of the radar is

Pulse radar transceiver common antenna, in the transmission pulse width of the time, the receiver and antenna feeder system is "disconnected", can not normally receive the target echo, after the transmission pulse of the antenna transceiver switch to return to the receiving state, also need a period of time t_0. During this time, radar is difficult to measure its range because it cannot receive echo signals properly. Therefore, the minimum measurable distance of the radar is

The common antenna for receiving and transmitting pulse radar is "disconnected" between the receiver and the antenna feeder system within the time of transmitting pulse width τ, so the target echo can not be received normally. After the transmitting pulse has passed, it also takes a period of time for the transceiver switch of the antenna to return to the receiving state_ 0。 In this period of time, it is difficult for radar to carry out range finding because it can not receive echo signal normally. Therefore, the minimum measurable range of radar is<br>
