Three-aperture inverse synthetic aperture radar moving targets imaging processing based on compressive sensing

Compressed sensing applied to weather radar

“…The scene is naturally sparse in the third dimension. The application of CS to ISAR imaging (Li et al 2012) is promising, especially since the number of pixels can be limited and the objects often show sparse reflections.…”

Complex‐valued interferometric inverse synthetic aperture radar image compression base on compressed sensing

“…To restore the image, the CS‐based method does not reconstruct the image directly, but reconstruct the frequency spectrum of the image first and then the image [15]. The spectrum can be reconstructed by solving the optimisation problem as follows where ε denotes the noise level in measured data and is determined by the noise energy.…”
