Effectual Decoy Airspace and Application of Natural Features Used as False Targets

Abstract

Abstract: For the application of natural features as false targets in laser decoy jamming，a calculation method for effectual decoy airspace is presented， and the proposal of typical natural features used as false targets was given.An analytic model of effectual decoy airspace is established，in which diffuse reflection false target is used as reference object.The effectual decoy airspace of typical natural features such as vegetation，gravel and soil is calculated based on the proposed model.Some suggestions on how to select the type，location and slope of natural features used as false targets are presented according to the distribution of effectual decoy airspace.The results show that the effectual decoy airspaces of gravel，soil and vegetation targets decrease in turn and are generally smaller than that of standard diffuse reflector.With the growth of laser beam incident angle， the effectual decoy airspace of natural features used as false targets decreases， and there is different degree of mirror shifting. When the natural features are selected as laser false targets， the gravel and soil targets should be preferentially selected， and the same type of natural features at lower altitudes provide better decoy effect. In addition，the selection of slope gradient should ensure that the cheating airspace formed by laser decoy on the slope covers the range of laser threat.
