Abstract:
A transmitter for a high resolution radar system, comprising:a microwave oscillator for providing at an output a continuous wave signal at a predetermined frequency, a pulse-former having an input coupled to said output of said oscillator and a first and a second switchable output whereby said oscillator signal can be applied to either output according to a control signal applied to a control terminal of said pulse-former, a switch driver having an output coupled to said control terminal of said pulse-former and operative to selectively switch said output of said pulse-former between said first and second outputs to provide at said first output a pulse comprising a number of said oscillator cycles indicative of a desired pulse to pulse interval and selected according to a range gated time delay, a bi-phase modulator having an input coupled to said first output of said pulse-former to provide at an output a bi-phase modulated signal, and an antenna coupled to said output of said bi-phase modulator for transmitting said bi-phase modulated signal according to a selected object range.
