Abstract

A system for tracking a range of a moving object is provided, the system comprising: at least two spaced apart broadband ultrasonic transmitters, each of said transmitters having a fixed and known location relative to one another; a first controller component connected to each of said transmitters and arranged to cause said transmitters to periodically emit at respective separate frequencies a burst of ultrasound; a broadband ultrasonic receiver; a second controller component operatively connected to said ultrasonic receiver to receive ultrasound signals from said transmitters; the second controller having, for each velocity within a range of velocities, a synthesised version of each burst of ultrasound at a given frequency as it would be expected to be received at said receiver when said object is moving at said velocity relative to a transmitter; the second controller being operable to periodically: for each transmitter: cross-correlate a received ultrasound signal with respective synthesized versions of bursts of ultrasound which are expected to be received directly by said ultrasonic receiver within a given time period after transmission by said transmitter; select a synthesized version with a highest cross-correlation peak as the version most accurately corresponding to the velocity of the moving object; select a time delay of a cross-correlation peak for said selected synthesized version as an indicator of a time of flight of said transmitted burst between said transmitter and said moving object; and calculate a range between said moving object and said transmitter based on said time delay; and calculate according to said ranges calculated for each transmitter, a location of said moving object relative to the locations of said transmitters.
