The optic-electronic countermeasure environment on the battlefield of loitering missile is analyzed. And the scenarios of laser, smoke screen, camouflage barrier and false target countermeasure in loitering missile testing are described. From the construction requirements of the optic-electronic countermeasure environment of loitering missile testing in actual combat evaluation, the key points of constructing the equipments required by these testing scenarios are analyzed systematically. It provides important references for optic-electronic countermeasure environment construction of loitering missile evaluation in the actual combat.
