The present disclosure relates to a method for detecting blockage of a radar sensor (105) by processing a radar signal (115, 116, 117) received by the radar sensor (105). The method comprises obtaining (S1) the radar signal (115, 116, 117), determining (S2) a range-Doppler representation (300) of the radar signal such that received radar signal energy (311) is represented as a function of distance (d0-d13) and relative velocity (v0-v7), determining (S4) predetermined azimuth angles (θ₁, θ₂, θ₃) for the radar sensor (105) and calculating (S31) a relative velocity (v0, v3, v5) for each predetermined azimuth angle (θ₁, θ₂, θ₃). The method further comprises obtaining (S5) a first distribution (301) and at least one other distribution (302, 303) of received energy (311) over distance in the range-Doppler representation (300) for a first azimuth angle (θ₁) and at least one other azimuth angle (θ₂, θ₃), generating (S7) a measure of similarity for the distributions, and detecting (S8) blockage of the radar sensor (105) if the measure of similarity satisfies a similarity criterion.
