7 Non-coherent and Pseudo-coherent Radar Systems
Fig. 7.5 Pseudo-coherent transmitter functional diagram (FrD—frequency divider; M—modulator; PA—power amplifier; Magn.—magnetron; Mx.—mixer; VCO—voltage-controlled oscillator; Int.—integrator; PD—phase detector (discriminator))
Fig. 7.6 Voltage-controlled oscillator tuning on transmitter signal
by equipment noise. This voltage tunes VCO circuits up to complete matching with
mixer signal (Fig. 7.6). Then, a signal delivers to attenuator and processing unit (PU).
