THE NONLINEAR RADON AND FOURIER TRANSFORMS
THE NONLINEAR RADON AND FOURIER TRANSFORMS
In order to deal with the nonlinear Radon transform, this chapter introduces a new type of Fourier transform: the nonlinear Fourier transform. This can be used to analyze various nonlinear Radon transforms. It is also useful in giving a new approach to wave front sets. (The quadratic case is similar to the FBI transform.)
Keywords: Fourier transform, nonlinear, wave front sets, quadratic, FBI transform
