ABSTRACT:
An FM radar system of more simple construction, smaller size, lower cost and improved performance is provided in which circulators of any type in the prior art are eliminated by constructing a transceiver comprised of a transmitting part and a receiving part, each formed on a common dielectric plate and having a dedicated transmitting antenna and a dedicated receiving antenna respectively. The antennas comprise planar array antennas, in contrast to the solid antennas used in prior art systems. The planar array antennas are also formed on the single dielectric plate. The transmitting part comprises a plurality of transmission antennas and a plurality of frequency multipliers coupled to said transmission antennas. The receiving part comprises a plurality of receiving antennas which are coupled to a plurality of switches through a plurality of mixers, frequency multipliers, and low noise amplifiers.
