MWIR Persistent Surveillance Performance for Human andVehicle Backtracking as a Function of Ground SampleDistance and Revisit Rate

摘要

Real MWIR Persistent Surveillance (PS) data was taken with a single human walkingfrom a known point to different tents in the PS sensor field of view. The spatialresolution (ground sample distance) and revisit rate was varied from 0.5 to 2 meters and1/8~(th) to 4 Hz, respectively. A perception experiment was conducted where the observerwas tasked to track the human to the terminal (end of route) tent. The probability of trackis provided as a function of ground sample distance and revisit rate. These results canhelp determine PS design requirements for tracking and back-tracking humans on theground. This paper begins with a summary of two previous simulation experiments: onefor human tracking and one for vehicle tracking.
