<p>The random frequency radar system comprises a wide band oscillator (1) whose random frequency output signal is mixed (2) with the output signal from a second oscillator thus providing pulsed transmission. The random frequency signal is mixed (3) also with the output signal for a third oscillator thus providing the local oscillation. The difference between the frequencies of the second and third oscillators is maintained at a constant value.</p> |
