Abstract
In a single-antenna time division control type FM-CW radar, an amplifier is provided in each signal path in a transmitting system and a receiving system, and the amplifier provided in the transmitting system and the amplifier provided in the receiving system are operated alternately in synchronism with transmit and receive timings, to perform switching between transmission and reception. The operation of the amplifiers is controlled by controlling the gain of each of the amplifiers. This configuration provides enhanced isolation between the transmitting and receiving systems, and prevents transmitting power from leaking into the receiving system through a transmit-receive switching section.
