Patent ID: 8009084

Claim:
A training radar display for decoding and displaying radar signals in different formats, comprising: a variable reference frequency means including a tape having a reference tone recorded thereon for providing a reference frequency being variable in accordance with rate of travel fluctuations of the tape, the variable reference frequency thereof is caused by fluctuations of the tape playback rate; means connected to the variable reference frequency means for generating a signal that is phase locked to the variable reference frequency; means for generating directing signals; means coupled to the phase locked signal outputting means and the directing signal's generating means for synthesizing a fine tuned signal based on the output signal of the phase locked signal generating means in accordance with the signals received from the directing signal's generating means; means providing video signals; means disposed to receive a video input signal from the video signal providing means for producing a sense directed gain controlled video signal; a plan position indicator converter coupled to receive the video output of the producing means and to process the video output from polar to rectilinear coordinates in accordance with signals received from the directing signal's generating means; means coupled to the plan position indicator converter and to receive the special purpose timing signal from the using means for presenting a display thereof; and a control panel connected to the directing signal's generating means, the video input producing means, the plan position indicator converter and presenting means to provide for input direction from the directing signal generating means.
