Abstract:
A method for dithering radar frames includes determining at least one of a chirp period Tc for radar chirps in a radar frame and a chirp slope S for radar chirps in the radar frame. In response to determining the chirp period Tc, a maximum chirp dither Δc(max) is determined, and for the radar frame N, a random chirp dither Δc(N) between negative Δc(max) and positive Δc(max) is determined. In response to determining the chirp slope S, a maximum slope dither Ψ(max) is determined, and for the radar frame N, a random slope dither Ψ(N) between negative Ψ(max) and positive Ψ(max) is determined. A radar sensor circuit generates radar chirps in the radar frame N based on the at least one of (1) the chirp period Tc and the random chirp dither Δc(N) and (2) the chirp slope S and the random slope dither Ψ(N).
