Radar Relay Data Compression System

Abstract

A method of reducing the amount of bandwidth required to transmit radar and artificial video over a radio link has been developed. The video obtained from an SP-lM radarand a flying spot scanner, covering a bandwidth of some1. 5 Mc, is compressed to a bandwidth of approximately 15 kc without loss of information. The compressed signal can be broadcast by a slightly modified TDQ Navy vhf transmitter.The receiving terminal consists of a standard vhf receiver and a decoder- indicator and is . conventional except for the synchronizing system for the rotational data.
