The Fourier Neural Operator (FNO) [1] is a neural operator with an integral kernel parameterized in Fourier space. This allows for an expressive and efficient architecture. Applications of the FNO ...
Abstract: Long time coherent integration (LTCI) for high-speed maneuvering targets in radar signal processing poses substantial difficulties due to the occurrence of range migration (RM) and Doppler ...
Abstract: This article has proposed a new and efficient Global Navigation Satellite System (GNSS) anti-interference method using fractional Fourier transform (FrFT) and notch filtering. An effective ...
S2FFT is a Python package for computing Fourier transforms on the sphere and rotation group (Price & McEwen 2024) using JAX or PyTorch. It leverages autodiff to provide differentiable transforms, ...
