Abstract:
1. A system for estimating the position of a radiation source in three dimensional space, the system comprising: a first radiation sensor for receiving radiation from the radiation source and for providing a first incident angle pair corresponding to the direction of the radiation source relative to the first radiation sensor, wherein the first radiation sensor includes: a second radiation sensor for receiving radiation from the radiation source and for providing a second incident angle pair corresponding the direction of the radiation source relative to the second radiation sensor, wherein the second radiation sensor includes: a processor for calculating the estimated position of the radiation source based on the first and second incident angle pairs, wherein: the processor is coupled to the first reference radiation detector and to the first and second direction radiation detectors for providing first and second incident angles wherein: the first incident angle corresponds to the first direction radiation intensity signal and the first reference radiation intensity signal; the second incident angle corresponds to the second direction radiation intensity signal and the first reference radiation intensity signal; and the first and second incident angles form the first incident angle pair;
