MEMS microwave communication signal detection and demodulation monolithic integrated system oriented to adaptive radar

Abstract

An MEMS microwave communication signal detection and demodulation monolithic integrated system oriented to adaptive radar is mainly composed of a six-port fixed beam coupler, a microwave frequency andpower detection module, a microwave phase detection module and a 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. The above structure simultaneously and synchronously detects the power, the frequency and the phase of the microwave signal and demodulates a modulated signal, and achieves the monolithic system integration of the MEMS microwave signal detection and demodulation oriented to adaptive radar.

Description

technical field [0001] The invention provides an adaptive radar-oriented MEMS microwave communication signal detection and demodulation monolithic integrated system, which belongs to the technical field of micro-electromechanical systems. Background technique [0002] Although the electronic countermeasure system of the existing radar can quickly and accurately identify the enemy radar system working in the common band, once the enemy radar signal is not obvious enough or is an unknown signal, the countermeasure effect will be seriously reduced. The new advanced adaptive radar electronic countermeasures include two key systems: adaptive radar reconnaissance and high-fidelity deception. Adaptive radar reconnaissance refers to radar signal detection, radar characteristic analysis, countermeasure pattern selection, countermeasure effect analysis and countermeasure Pattern adjustment and other links constitute a closed-loop system; high-fidelity deception refers to the precise s...

Problems solved by technology

However, in the existing technology, the detection of the power, frequency and phase of the microwave signal is measured separately, resulting in the shortcomings of the entire system, such as large volume, high power consumption, narrow frequency band, and low integration. In addition, for relatively For complex microwave modulated signals, traditional communication technology needs to use another system for demodulation, which increases a lot of cost and makes it difficult to use in adaptive radar
