Abstract :
A two-element time-modulated array system is configured to operate as a direction finding antenna. The signal from each element of the array is time switched to provide a phase modulated output in which the depth of modulation is dependent on the angle of arrival of the received signal. Details of an experimental system designed to operate at 2400 MHz are presented and the results are compared to theoretical predictions.
