Positioning Mobile Vehicle by Using Super-Short Baseline with AM Ultrasonic Beacon
To position a mobile vehicle, it is presented to improve conventional ultra-short baseline by using super-short baseline with AM ultrasonic beacons. The array distance increases about 10 times, and errors caused by timedelay is eliminated in the proposed method. To estimate the key phase differences in the proposed method, a measurement equation based on the elliptical area which is used for estimation of the parameters is put forward. The experiment set-up is established, and experiments were performed. Experimental results indicate that accuracy is close to±3mm, and does that the SSBL with AM ultrasonic beacons in positioning is valid.
