Airborne radar detecting and recording system
Abstract
Abstract A RADAR DETECTION AND RECORDING SYSTEM FOR PROVIDING A PERMANENT RECORD OF CERTAIN DATA REGARDING RADAR SIGNALS DETECTED DURING AN AIRBORNE MISSION AND INCLUDING MEANS FOR SUBSEQUENTLY REPRODUCING SAID DATA. A SIGNAL ANALYSER RESPONSIVE TO A RADAR DETECTION MEANS ANALYZES THE DETECTED SIGNALS AND DIVIDES THEM INTO COMPONENT SIGNALS WHICH ARE SUITABLE FOR DRIVING AN AZIMUTH INDICATOR MEANS. THE COMPONENT SIGNALS ARE SAMPLED AND MODIFIED BY AN INTERFACTING MEANS WHICH CONVERTS THE SIGNALS NORMALLY USED TO ENERGIZE THE INDICATOR MEANS INTO A CODED FORM SUITABLE FOR RECORDING ON A PLURAL CHANNEL MAGNETIC RECORDING DEVICE. THE RECORDED SIGNALS MAY THEN SUBSEQUENTLY BE UTILIZED TO RECONSTRUCT THE SIGNALS ORIGINALLY USED TO DRIVE THE AIRBORNE INDICATOR MEANS.
