A method for estimation of many-dimensional images with super-Rayleigh resolution in processing of echo signals at coherent sounding

A. A. Chizhov


A new method called NOSE (nonorthogonal signals estimation) is suggested for assessment of many-dimensional (time-space-Doppler type) amplitude-phase images, particularly, multiple lumped targets. When using this method, the maximum possible resolving capacity of the radar system is limited only by the signal-to-noise ratio. An analytical expression of the correlation matrix of noise in image is deduced. The soundness of the method at typical signal-to-noise ratios is confirmed by the mathematical simulation method.
