    Abstract:

    A denoised and wide swath thermal imaging technology based on low rank matrix approximation ( LRMA) was proposed to solve the problem of low signal-to-noise ratio ( SNR) of thermal imaging system noise in strong background and weak signal scene. This technology utilized array whisk broom mode to realize wide swath imaging and construct strict observations. The denoising low-rank matrix of observations was solved via weighted nuclear norm minimization ( WNNM) . Experiments showed that the technology had high peak signal to noise ratio ( PSNR) and denoising robustness. Both of imaging width and detection sensitivity were improved. The technology has certain application value in the field of weak target recognition and large area investigation.
