Problems solved by technology
However, the detection of microwave signals is currently carried out by using some large-scale devices, which have a series of problems such as large volume, high power consumption, narrow frequency band and low integration. Our focus is on the power, phase and frequency of microwave signals, etc. The measurement of parameters, in addition, the demodulation of the microwave modulated signal is also one of the key points

Abstract
The invention discloses an adaptive radar phase comparison method cantilever beam direct micro nano microwave detection and demodulation single chip system, which is mainly composed of four parts of asix-port cantilever coupler, a microwave frequency detection module, a microwave phase detection module and a microwave power detection and demodulation module. The adaptive radar is composed of an antenna, a receiving, transmitting and converting circuit, an MEMS microwave detection and demodulation single chip integration system, a signal memory, a signal analyzer, a microwave signal reconstruction, microwave signal modulator and a microwave signal power amplifier. The thermal conductivity of a nano thermocouple is lower than that of the traditional material. By adopting the nano thermocouple, the thermoelectric conversion efficiency can be effectively improved, and the measurement sensitivity is greatly improved. Integration of the microwave signal power detection module, the microwavesignal frequency detection module and the microwave signal phase detection module can be completed; simultaneous and synchronous detection on the microwave signal power, the microwave signal frequency and the microwave signal phase at the same moment can be completed; demodulation on already-modulated signals can be completed; and adaptive radar phase comparison method cantilever beam direct micro nano microwave detection and demodulation single chip system is realized.
Description
technical field [0001] The invention proposes a cantilever beam direct micro-nano microwave detection and demodulation monolithic system by adaptive radar phase comparison method, which belongs to the technical field of micro-nano electro-mechanical systems. Background technique [0002] Modern adaptive radar mainly includes two system directions: adaptive radar reconnaissance and high-fidelity deception. Adaptive radar reconnaissance is composed of radar signal detection, radar characteristic analysis, countermeasure pattern selection, countermeasure effect analysis, and countermeasure pattern adjustment. A closed-loop system, and high-fidelity deception refers to the precise reproduction and forwarding of the enemy's signal, so that the deception signal can match the enemy's radar signal and enter the enemy's radar signal receiving circuit at the same time to achieve the purpose of deceiving the signal target. However, at present, the detection of microwave signals is carr...
