Design of Dual-channel Circuit of P-Band Instantaneous Polarization Radar
First of all, the detection theory of the Instantaneous Polarization Radar is introduced. The overall structure of dual-channel circuit has been designed. The principle part of RF system consists of antenna arrays and the dual-channel receiving and transmitting circuit. Si4133 chip used as the core design of the high stability, fully coherent frequency synthesizer as Instantaneous Polarization Radar’s frequency source. Then the structural design of inverters pieces is discussed, clear frequency convert program is reasonable. ADEX-10L devices use to produce high vibration isolation mixers. The dual-channel receiver components focuses on the development of voltage-controlled gain amplifier based on the AD8367 chip, and the amplitude-frequency characteristics, phase frequency characteristics and dual-channel consistency were tested. The introduction of the automatic power balance technology to ensure that the two-channel transmitter power balance.
