Abstract :
The paper describes a new system of fm radar by which both the range and the speed of the target can be accurately measured. The "fixed error," which is a characteristic of fm radar apparatus now in use, has been eliminated, affording correct measurement of ranges, even if they are very short. The functioning of the new system has been investigated experimentally and proven to be very successful. Consequently, the author in cooperation with the Hasler Laboratories in Bern, Switzerland, developed a low-range airplane altimeter patterned after the new system.
