First Claim
Patent Images
1. A method for determining the position of an object in a system comprising a sensor arranged at a determinable location, the method comprising:
- obtaining a time of arrival for a signal received at the sensorcalculating a slant range from the object to the sensor based, at least in part, upon the obtained time of arrival;
wherein calculating the slant range further comprises;
adding a known distribution of noise to the time of arrival;
prior to calculating the slant range; and
determining a position vector based, at least in part, upon the calculated slant range and the location of the sensor.

Abstract
A method and system for determining the location of an object. The system may implement a number of sensors at different locations that are positioned to receive a transmitted or reflected signal from the object. Also disclosed is a system and method of calculating object position based upon the time difference of arrival (TDOA) from each sensor, or the relative time difference of arrival (RTDOA). A known distribution of noise is added to the time of arrival (TOA) prior to calculating the object position.
