The system is mainly formed by a six-port cantilever beam coupler, a microwave frequency detection module, a microwave phase detection module, and a microwave power detection and demodulation module. An adaptive radar is formed by an antenna, a transmit-receive conversion circuit, a MEMS microwave detection and demodulation single chip integration system, a signal memory, a signal analyzer, microwave signal reconstruction, a microwavesignal modulator, and a microwave signal power amplifier. Through the above structure, the three detection modules of the power, frequency and phase of a microwave signal can be integrated, and the simultaneous synchronous detection of the power, frequency and phase of the microwave signal at the same time and the demodulation of a modulated signal can be completed, and the adaptive radar phase comparison method cantilever beam microcomputer electric microwave detection and demodulation single chip system is realized.

Description

technical field [0001] The invention proposes an adaptive radar phase comparison cantilever beam micro-electromechanical microwave detection and demodulation monolithic system, 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. To improve the countermeasure effect, it is necessary to reproduce the countermeasure signal with high precision. Therefore, microwave communication signal detection and demodulation play a very important role in adaptive radar equipment. At present, most microwave devices work in the GHz frequency band. The wavele...
