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

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.
