Claim 1
Independent Claim
180 words
A RADAR DATA CONVERTER FOR USE WITH AN AIRCRAFT RADAR SYSTEM HAVING AN ANTENNA VERTICAL CAPABILITY PROVIDING A DISPLAY OF TERRAIN PROFILE AT THE AIRCRAFT AZIMUTH HEADING, COMPRISING IN COMBINATION: SAWTOOTH GENERATOR MEANS PROVIDING A RANGE SAWTOOTH VOLTAGE OUTPUT HAVING AN AMPLITUDE WHICH IS A FUNCTION OF RANGE OF THE TRAGET, PEAK DETECTOR MEANS CONNECTED TO SAID SAWTOOTH GENERATOR MEANS PROVIDING A D.C. VOLTAGE OUTPUT HAVING AN AMPLITUDE WHICH VARIES DIRECTLY WITH THE PEAK VOLTAGE OF SAID RANGE SAWTOOTH, A PLURALITY OF STORAGE MEANS, FIRST RELAY MEANS COUPLING SAID PEAK DETECTOR MEANS TO SAID PLURALITY OF STORAGE MEANS WHEN THE RADAR ANTENNA IS ALIGNED WITH AIRCRAFT HEADING, SECOND RELAY MEANS CONNECTED BETWEEN SAID FIRST RELAY MEANS AND EACH OF SAID PLURALITY OF STORAGE MEANS COUPLING THE OUTPUT OF SAID PEAK DETECTOR MEANS SUCCESSIVELY TO EACH OF SAID PLURALITY OF STORAGE MEANS AT A RATE PROPOPRTIONAL TO AIRCRAFT SPEED WHEREBY THE OUTPUT VOLTAGE OF SAID PEAK DETECTOR MEANS WHICH IS PROPORTIONAL TO RANGE IS SUCCESSIVELY STORED IN EACH OF SAID PLURALITY OF STORAGE MEANS AT A RATE PROPORTIONAL TO AIRCRAFT VELOCITY.
