To design the flight attitude stability control loop of gun-launched unmanned aerial vehicle(UAV) with longitudinal and lateral directional 2D linear model established in terms of the static stability condition during the cruise,the improved proportional feedback control method is employed to achieve the require of the settling time and steady-state precision.

This paper introduces the current development of the US Navy s submarine-launched unmanned aerial vehicles (UAVs), and probes into its operational modes of ocean operation, anti-submarine operation and air defense operation.

Then according to the quantitative formula of decoy effect of anti-radiation UAV,the validity of decoy effect under this kind of layout deployment is verified through simulations,which provides theoretical basis for the design and deployment of anti-radiation UAV countermeasure.

Presently,anti-radiation UAV has become the important aim of the aerial defence weapon.

Based on the theoretical analysis of shoot and condition kill probability for anti-radiation UAV,a method of calculating killprobability for anti-radiation UAV againstsurface radar target was proposed.

In view of the anti-radiation unmanned aerial vehicle(UAV)searching,attacking and suppressing covered radars in irregular and define region,this paper puts forward the path layout index——coverage region,and makes use of the hybridization and variation of genetic algorithms to araise the search path which meets the mission needs and flexiblity of anti-radiation UAV.

As a new hard kill weapon in the electronic warfare(EW),the anti-radiation unmanned aerial vehicle(UAV) has become an important defense penetration force.
