Abstract

An adaptive radar phase-comparing method fixed beam micro-nano microwave detecting and demodulating monolithic system of the invention is mainly composed of four parts including a six-port fixed beamcoupler, a microwave frequency detection module, a microwave phase detection module and a microwave power and demodulation module. The adaptive radar consists of an antenna, a transmitting-receiving conversion circuit, a MEMS microwave detection and demodulation monolithic integrated system, a signal memory, a signal analyzer, a microwave signal reconstructor, a microwave signal modulator, and a microwave signal power amplifier. An indirect heating microwave power sensor uses polycrystalline silicon nanowire clusters to form a thermocouple arm, has a thermal conductivity lower than that of a conventional bulk material, has high thermoelectric conversion efficiency, can greatly improve the sensitivity of the microwave detection system, can simultaneously and synchronously detects the power,the frequency and the phase of the microwave signal and demodulates a modulated signal, and achieves the adaptive radar phase-comparing method fixed beam micro-nano microwave detecting and demodulating monolithic system.

Description

Technical field [0001] The invention proposes an adaptive radar phase comparison method for a fixed-supported beam micro-nano microwave detection and demodulation single-chip system, which belongs to the technical field of micro-nano electronic mechanical systems. Background technique [0002] At present, in the field of microwave communication, especially in the application of adaptive radar, the detection of microwave signals uses some large-scale devices to measure, and there are a series of problems with large volume, high power consumption, narrow frequency band and low integration. , And our focus is on the measurement of parameters such as the power, phase and frequency of microwave signals. In addition, demodulation of microwave modulated signals is also one of the key points. As we all know, most of the receiving frequency bands of adaptive radar are in the GHz frequency band. With the continuous increase of frequency, the signal wavelength is closer to the size of vario...

Problems solved by technology

In addition, for more complex microwave modulation signals, traditional communication technology needs to use another system for demodulation, which will also cause the above problems, and at the same time increase a lot of cost, making it difficult to use in adaptive radar
