Paper Abstract

In this paper we address these problems. 1) Two stationary observers with two sensors independently search for a stationary target. Each sensor is characterized by individual search parameters (p∞, τ) which are different either because the sensors are at different ranges or are different because the sensors are at the same range but have different properties. The target is said to be detected when the first observer detects the target. Using this definition for time to detect, we derive an analytical expression for the mean detection time. 2) If multiple observers independently search an image obtained from a single sensor how does the mean time until the first observer detects the target vary with the number of observers. 3) If multiple observers independently search an image obtained from a single sensor how does the probability of detection vary with the number of observers. Here the target is said to be detected if any of the observers detect the target. 4) For the problem of two stationary observers searching independently for a stationary target we found the probability density function for the time to detect.
