Abstract
Abstract Precision and verification track processors receive radar information from receivers which may be fed by a test target generator. The analog outputs of the processors are simultaneously applied to a multiplexer. The analog output of the multiplexer is converted by an analog to digital converter whose output is fed through an output buffer to control switch buffer and to a computer. A track gate generator, a discrimination gate generator, and the test target generator are all controlled by the control switch buffer. The gate generators in turn control the operation of the processors, multiplexer, analog to digital converter, and output buffer.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
A converter system comprising: two processor means having inputs connected to receive different groups of analog signals from a plurality of received analog signals; a time sharing means; said processor means having outputs connected to inputs of said time sharing means; an analog to digital converter means having outputs; utilization means connected to said outputs of said converter; said time sharing means having an output in which said output signals of said processor means are fed one at a time to said converter means for conversion to a form usable by said utilization means; gate generating means connected to said processor means, said time sharing means, and said converter means so as to control the operation of these means; said time sharing means comprising a multiplexer whose timing is controlled by said gate generating means; wherein said plurality of received signals are radar return pulses which are derived from a radar receiver unit, and said gate generating means being connected to the receiver unit so as to provide range gates thereto.
