Abstract

The invention provides a phase comparison method slot-coupling MEMS microwave detection and demodulation single-chip system in adaption radar, which is mainly composed of a six-port slot coupler, a microwave frequency and power detection module, a microwave phase detection module and a demodulation module. The adaption radar is composed of an antenna, a transceiver conversion circuit, a phase comparison method slot coupling MEMS microwave detection and demodulation single-chip system, a signal memory, a signal analyzer, a microwave signal reconstruction, a microwave signal modulator and a microwave signal power amplifier. With the above structure, synchronous detection of the power, frequency and phase of the microwave signal at the same time and demodulation of the modulated signal can beachieved, realizing the phase comparison method slot-coupling MEMS microwave detection and demodulation single-chip system in the adaption radar.

Description

technical field [0001] The invention proposes a phase-comparison method slot-coupling MEMS microwave detection and demodulation monolithic system in an adaptive radar, which belongs to the technical field of micro-electromechanical systems. Background technique [0002] Although the electronic countermeasure system of the existing radar can quickly and accurately identify the enemy radar system working in the common band, but this kind of matching, jamming and deception of the enemy radar signal based on the known threat, once the enemy If the radar signal is not obvious enough or is an unknown signal, the countermeasure effect will be seriously reduced. It can be seen that microwave communication signal detection and demodulation occupy a very important position in adaptive radar equipment. With the continuous increase of the frequency band of the microwave communication system, the wavelength of the signal is getting closer and closer to the size of various components in ...
