High-resolution Infrared or Millimeter Wave Imaging Based on Compressed Sensing
基于压缩传感的红外或毫米波无源高分辨率成像

An passive infrared or millimeter wave imaging system based on the theory of compressed sensing is designed. Compressed sensing is a technology using sparse or compressed priority information to acquire and reconstruct signals. It can sample signals at a rate much lower than the Nyquist sampling rate and implement high precision reconstruction of the signals. The above designed system has overcome the shortcomings of the traditional systems and can conduct its imaging according to the theory of compressed sensing. The simulation result shows that the system has good imaging performance, its peak signal to noise ratio and resolution are improved and the data required to be stored are reduced greatly.
