Abstract:
A radar system transmitting a signal of given carrier frequency which is quency modulated at a given rate and wherein the nature of the target return is utilized to eliminate sea and ground clutter. The reflected signal from a hard target has a unique modulation imposed on it by the interference of the incident and reflected waves and this unique modulation is converted to the modulated voltage thereby permitting the use of a video amplifier having a narrow bandwidth.
