1. A method comprising:
filtering hitbox radar targets from field of view (FOV) radar targets, the FOV radar targets detected by one or more radars operably coupled to a body of a vehicle, the hitbox radar targets filtered based on a range and an azimuth angle, the hitbox radar targets being within a a predetermined area in front of the vehicle;
filtering the hitbox radar targets to select substantially zero-Doppler-speed hitbox radar targets;
tracking the substantially zero-Doppler-speed hitbox radar targets to verify whether positions of the substantially zero-Doppler-speed hitbox radar targets are constant;
determining a number and distribution of the substantially zero-Doppler-speed hitbox radar targets; and
determining a vehicle first stationary status based on whether the number of substantially zero-Doppler-speed hitbox radar targets are moving in synchronization.
