An indirect heating type microwave power sensor adopts a polycrystalline silicon nanowire cluster to form a thermocouple arm, and the thermal conductivity is lower than that of a traditional bulk material, the advantage of high thermoelectric conversion efficiency is achieved, and the sensitivity of the microwave detection system can be greatly improved,the power, the frequency and the phase of the microwave signal can be synchronously detected at the same time, and the modulated signal can be demodulated, so that the self-adaptive radar phase comparison method cantilever beam micro-nano microwave detection and demodulation monolithic system is realized.

Description

technical field [0001] The invention proposes an adaptive radar phase comparison cantilever micro-nano microwave detection and demodulation monolithic system, which belongs to the technical field of micro-nano electromechanical 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, the current detection of microwave signals is to use some large-scale device...

Problems solved by technology

However, the current detection of microwave signals is to use some large-scale devices for measurement. There are 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. In addition, the demodulation of microwave modulated signals is also one of the key points
