Abstract
The purpose of this research is to design a digital phased array for receiving and tracking a 2.4 GHz FM video signal from an unmanned air vehicle. The tracking is done using a monopulse technique. Various numbers of elements were simulated to access the pattern coverage. The beamforming and demodulation are performed digitally by a computer. Several antenna architectures were studied and the requirements for hardware components such as the analog-to-digital converters and amplifiers are specified. Several methods for generating the carrier signal for the local oscillator are also discussed. They include an independent local oscillator, a voltage controlled oscillator with feedback (i.e., a phased locked loop) and mixing with a phase shifted copy of the received signal (Bilotti's method).
