Claim:
A method for analyzing performance of a system of sensors, which method comprises analytical calculation of a sensor system's measurement characteristics at each point in a given geographical area, the method comprising: obtaining performance parameters from N S sensors that are in the system, the performance parameters comprising: p ss,j =a detection probability per scan for targets with a particular target area for the sensor N S =i; R j =measurement accuracy expressed as a covariance matrix for the sensor N S =i; T j =searching time for a search area for the sensor N S =i, and; P fa,j =a probability of false alarms for a sensor N s =i; calculating a set of analytical performance parameters for the system using the performance paramaeters being fused, the calculating of the analytical performance parameters being performed irrespective of different measurement charictaristics of the sensor in the system, the calculating of the analytical performance parameters including evaluating the following expressions: T j = ( ∑ i = 1 N S ⁢ ⁢ T i - 1 ) - 1 ( 7 ⁢ - ⁢ 2 ) 1 T e ⁢ ⁢ j = ∑ i = 1 N S ⁢ p s ⁢ ⁢ s , i T i ⁢ ( 7 ⁢ - ⁢ 3 ) p s ⁢ ⁢ s , j = T j T e ⁢ ⁢ j , ⁢ ( 7 ⁢ - ⁢ 4 ) 1 T e ⁢ ⁢ i = p s ⁢ ⁢ s , i T i ⁢ ( 7 ⁢ - ⁢ 5 ) ⁢ μ i = T e ⁢ ⁢ j T e ⁢ ⁢ i ⁢ ( 7 ⁢ - ⁢ 6 ) ⁢ R j = { ∑ i = 1 N S ⁢ μ i ⁢ R i - 1 } - 1 ⁢ ( 7 ⁢ - ⁢ 7 ) ⁢ p f ⁢ ⁢ a , j = { ∑ i = 1 N s ⁢ p f ⁢ ⁢ a , i T i } ⁢ T j ( 7 ⁢ - ⁢ 8 ) where T j , 1 T e ⁢ ⁢ j , p ss,j , μ i , R j and p fa,j comprise the analytical performance parameters, where N s stands for the number of sensors in the system, and where the subscript j stands for joint; using the analytical performance parameters for analysis of the sensor system's performance.
