MULTIFUNCTIONAL SMALL-SIZED RADAR SYSTEM FOR AIRCRAFTS

摘要

FIELD: radio engineering, communication.;SUBSTANCE: multifunctional small-sized radar system for aircraft consists of a radio-frequency module (RFM) and an on-board computer (OBC). The RFM consists of a transceiver module and an antenna module including a waveguide-slot antenna array (WSAA), a drive, a four-channel microwave receiver, a circulator. The transceiver module consists of a transmitter, an intermediate frequency receiver (IF-receiver), and a synthesizer of frequency and clock signals (SFCS). The SFCS consists of a power supply, a control module, an emission signal generating module F₀, a reference oscillator, a reference frequency oscillator and a base frequency generator.;EFFECT: expanding the bandwidth.;3 dwg
