T/R Module failure correction in active phased array antenna system

Author(s): Rizwan H.Alad

This paper presents particle swarm optimization (PSO) technique to mitigate the radiation performance of an active phased array antenna under the condition that a selective number of radiating elements have malfunctioned. The PSO algorithmhas been applied to determine the excitation coefficients of array elements yielding optimum performance of an active phased array antenna with a few elements which have failed. Simulated radiation performance has been presented for different cases of failure.
