Abstract

An adaptive radar ratio 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 ratio method slot-couplingdirect micro-nano microwave detecting and demodulating monolithic 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. 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 structurecan integrate the power detection module, the frequency detection module, and the phase detection module of the microwave signal, and can simultaneously and synchronously detects the power, the frequency and the phase of the microwave signal and demodulates a modulated signal.

Description

technical field [0001] The invention proposes a ratio method gap coupling direct micro-nano microwave detection and demodulation system in an adaptive radar, which belongs to the technical field of micro-nano electromechanical systems. Background technique [0002] The new advanced adaptive radar electronic countermeasures include the two key systems of adaptive radar reconnaissance and high-fidelity deception. Adaptive radar reconnaissance is able to adaptively adjust the confrontation style and parameters according to the structural characteristics of unknown radar signals, analyze the working status and performance of the radar system, in order to achieve the best confrontation effect; high-fidelity deception refers to the The unknown radar signal is accurately stored, copied, modulated and forwarded, so that the characteristic difference between the deception signal and the enemy radar signal is as small as possible, forming a high-fidelity electronic false target that m...
