Method and system for determining possible geographic location of at least one hypothesized undetected target within a geographic volume of interest

摘要

A sensor monitoring system 100 and method are provided for determining a possible geographic location of at least one assumed undetected target 1a-1n within a geographic volume 200 of interest, at a first time point t1, Dividing the geographical volume of interest 200 into sections 10; Assuming the presence of undetected targets 1a to 1n assumed at the geographic location within each section 10; And initiating the creation of a pattern (2) defining at least one possible geographic location of the hypothesized undetected target, the pattern at least partially extending around the geographic location of the hypothesized undetected target (1a-1n). Being, an initiating step is performed; The geographic extension of the pattern includes the categories of assumed undetected targets 1a to 1n; And the amount of time elapsed from the first time point t1. Also, at a second time point t2, determining a geographic location 205 within the geographic volume of interest 200 where the sensor signal indicates the absence of a target; And removing the pattern 2 from the geographic location 205 where the sensor signal indicates the absence of the target.
