Abstract: Systems and methods for adaptive Doppler window function selection are provided and include a radar system that determines whether a dominant target is present in a sensing environment of the radar system based on received radar signals reflected from an object and selects either a first window function or a second window function based on whether the dominant target is present in the sensing environment. The radar system performs a Doppler fast Fourier transform (FFT) procedure with the selected window function. The first and second window functions have different signal-to-noise ratio (SNR) degradations when used in performing the Doppler FFT procedure. The radar system also determines information about the object based on performing the Doppler FFT procedure, the information including at least one of a location, a size, an orientation, a velocity, and an acceleration of the object.
