Abstract: To ensure the target within view field is the precondition of the tracking measuring equipment working normally, which is described by probability in engineering. A precise method of optical equipment detection probability was addressed aiming at the maneuverable targets, an exact description method of the whole airspace detection according to optical sensor was put forward, and a detection probability model for optical target was set up. A calculation method suited the model was confirmed,which was given by simulation analysis of the algorithm's calculation performance, the influence of model various parameters on algorithm was analyzed, and a comparison was given between traditional and new description method of whole airspace detection. The simulation result ilustrates that the detection probability model has higher precision, and the confirmed algorithm is one possible realization for the Engineering Application of this model.
