Abstract
A continuous wave radar system comprises a transmitter section (1), a receiver section (2) and a common transmit/receive aerial (3). A directional coupler (12) is used to couple the transmitter section output (9) to the aerial (3) and to couple the aerial (3) to a first input (5) of a mixer (4) included in the receiver section (2). A second input (6) of the mixer (4) is fed with a reference signal from the transmitter section (1) via a fourth port (17) of the coupler (12), thereby usefully utilizing at least some of the transmitter power which would be wasted were the fourth port (17) merely terminated in a matched impedance.
