| Abstract: | A new calculating method of detection probability for IR warning system was proposed.The mathematical model of calculating process was set up corresponding to the optical system with given parameter.The model showed that the instant detection probability density of unknown target on the different motion condition had direct ratio relation with the rotational speed of IR warning system,kinematic velocity of target and distance between target and system respectively.Taking human eyes as the acceptor,the influ... |
