Abstract

An adaptive radar phase-comparing method slot-coupling direct micro-nano microwave detecting and demodulating system of the invention is mainly composed of a six-port slot coupler, a microwave phase detection module, a microwave frequency and power detection module and a demodulation module. The adaptive radar consists of an antenna, a transmitting-receiving conversion circuit, a phase-comparing method slot-coupling direct micro-nano microwave detecting and demodulating monolithic system, a signal memory, a signal analyzer, a microwave signal reconstructor, a microwave signal modulator, and amicrowave signal power amplifier. An indirect heating microwave power sensor uses polycrystalline silicon nanowire clusters to form a thermocouple arm. The polycrystalline silicon nanowire clusters have thermal conductivity much lower than that of a conventional bulk material, have high thermoelectric conversion efficiency, and can greatly improve the sensitivity of the microwave detection system.The above structure can integrate the power detection module, the frequency detection module, and the phase detection module of the microwave signal, can simultaneously and synchronously detects thepower, the frequency and the phase of the microwave signal and demodulates a modulated signal.

Description

technical field [0001] The invention proposes a direct micro-nano microwave detection and demodulation system for phase-comparison slot coupling in self-adaptive radar, which belongs to the technical field of micro-nano electromechanical systems. Background technique [0002] The microwave communication system accepts the frequency of the frequency band to increase continuously, and the wavelength of the signal is getting closer and closer to the size of various components in the circuit. Therefore, measuring the phase of microwave signals becomes an important task. However, in the existing technology, large-scale devices such as counters are used to measure the power, frequency and phase of microwave signals. For complex microwave modulated signals, traditional communication technology needs to be demodulated. Using another system will also cause problems such as large volume, high power consumption, narrow frequency band and low integration of the entire microwave measure...

However, in the existing technology, large-scale devices such as counters are used to measure the power, frequency and phase of microwave signals. For complex microwave modulated signals, traditional communication technology needs to be demodulated. Using another system will also cause problems such as large volume, high power consumption, narrow frequency band and low integration of the entire microwave measurement system, and also increase a lot of costs
