UAV Digital Tracking Array Design, Development and Testing
Abstract
This thesis carried out the design and development of an integrated array and receiver processor that utilizes advanced techniques of Robust Symmetric Numeric System (RSNS) and monopulse Digital Beamforming (DBF) to accurately track a UAV using commercial-off-the-shelf (COTS) equipment. This was based on previous work done using virtual spacing RSNS and digital beamforming to extend the method to a functional six element array with direction finding and tracking capability. The six-element antenna array and direct-conversion receiver were developed and tested to retrieve a FM-modulated video signal encoded using the NTSC format. This thesis addresses system-level design tradeoffs, as well as hardware and software design, development and testing. A bench top test was conducted to test the functionality of the NTSC decoding and FM software modules developed and a comprehensive test was done in an anechoic chamber to characterize the array's capability in DF using RSNS and monopulse DBF.
