The development of electronic countermeasures against target track radars is both an expensive and time-consuming process. One method of cutting development time is to use genetic algorithms to develop electronic countermeasures using integrated software models of the target track radar and the jammer. This paper demonstrates the feasibility of this idea by using a genetic algorithm to optimize the parameters of a range gate pull-off electronic countermeasure technique to break the target lock of a generic radar split gate range tracker.
The computation or prediction of plane wave back scattered field is one of the major design considerations of future aircraft and weapon systems. The task of computing the electromagnetic backscattered field of an airframe structure is by no means a new endeavor. Whereas predicting a minimal backscattered field return under the manipulation of airframe geometry in the context of multidisciplinary design is considered the most prudent approach to obtain the optimal solution and is a new endeavor. The objective of this paper is to develop a mathematical method to couple the backscattered field with the defined aerodynamic performance constraints in the design process of future airframes. This paper will address the coupling of the electromagnetics discipline in a Multidisciplinary Design Optimization (MDO) scheme that includes the mathematical optimization of aerodynamics, or Aero discipline, including the coupling effects of aerodynamic performance (maximum value) with backscattered field return (minimum value) of a Zeroth (0th) Order Mode wing planform.
