In this study, demodulation of two AM signals modulated using different frequencies and received by one time-modulated linear array is presented. In addition to sidelobe level control, fundamental harmonic beam is steered to desired direction to achieve the reception of both message signals, using pulse difference technique and variable pulse amplitude approach as excitation strategy for time modulation. It is asserted that two messages from different directions with different frequencies may be received simultaneously via a time-modulated array. |
