PURPOSE:To prevent mutual interference positively with a simple construction when another radar of similar frequency is located at a short distance from one radar by securing synchronization in the transmission cycle between the two radars utilizing waves transmitted from the other radar. CONSTITUTION:In the initial state, a selector switch 3a is connected to a detection circuit 4 to detect signals from another radar and as the signals are detected from the radar, a control signal is sent to a driving circuit 8 from the circuit 4 to turn the switch 3a to a received signal processing circuit. Then, the output of the circuit 4 is delayed by a slightly shorter time than the transmission cycle thereof and provided to the circuit 8 to turn the switch 3a to the circuit 4. This enables signals transmitted from the other radar to be always detected and hence, kept from moving to the received signal processing circuit. |
