ABSTRACT:
Disclosed is a radar apparatus including the circuitry for synchronizing a first and second pulse train, having the same pseudo random coding. The apparatus comprises a programmable delay responsive to a control signal for selectively advancing and retarding a pulse train by monotonic increments. A positive and negative range gate is utilized in passing the video signals in opposite senses in order to generate a command signal for bringing the pulse trains in synchronization.
