Abstract
1. A radar signal code generator comprising: a. first oscillator means comprising an output terminal for producing, at id terminal, a continuous signusoidal wave having a continuously varying frequency; and b. pulse generator means operatively connected to said first oscillator means output terminal for producing a plurality of pulses, each of which consists of a constant frequency carrier wave, the initiation of each of said pulses occurring at a predetermined time interval after a respective cycle of said sinusoidal wave from said first oscillator means reaches a selected phase value.

A radar signal code generator comprising:
- a. first oscillator means comprising an output terminal for producing, at said terminal, a continuous sinusoidal wave having a continuously varying frequency;
- and
- b. pulse generator means operatively connected to said first oscillator means output terminal for producing a plurality of pulses, each of which consists of a constant frequency carrier wave, the initiation of each of said pulses occurring at a predetermined time interval after a respective cycle of said sinusoidal wave from said first oscillator means reaches a selected phase value.
A radar signal code generator comprising:
- a. a first oscillator for generating a first signal;
- b. a second oscillator which is frequency variable and having a control input which is operatively connected to said first oscillator in such a manner that the frequency of the output of said second oscillator is dependant on the instantaneous amplitude of said first signal;
- and
- c. pulse generator means for producing a series of carrier wave modulated pulses and operatively connected to said second oscillator in such a manner that the repetition rate of said pulses is equal to the instantaneous frequency of the output of said second oscillator.
