Abstract EN
Three issues regarding sensor failure at any position in the antenna array are discussed.
We assume that sensor position is known.
The issues include raise in sidelobe levels, displacement of nulls from their original positions, and diminishing of null depth.
The required null depth is achieved by making the weight of symmetrical complement sensor passive.
A hybrid method based on memetic computing algorithm is proposed.
The hybrid method combines the cultural algorithm with differential evolution (CADE) which is used for the reduction of sidelobe levels and placement of nulls at their original positions.
Fitness function is used to minimize the error between the desired and estimated beam patterns along with null constraints.
Simulation results for various scenarios have been given to exhibit the validity and performance of the proposed algorithm.
