Design and Implementation of Guidance Laws for Intercepting Targets with Towed Decoys

To attack non-maneuvering targets with towed decoys, a new compound guidance concept for head-on interception is proposed. Considering the conical blind area in front of decoy, we formulate a head-on engagement scenario: where the attacking missile enters the blind area of the decoy to avoid the radar jamming from the towed decoy and then attacks the target directly. Based on some common assumptions, the guidance laws for the missile inside and outside the blind area is presented respectively. Moreover, a sufficient condition for the existence of head-on engagement geometry is derived. Finally, numerical simulation is conducted, and the results show satisfactory performance of the compound guidance strategy.
