The Register Transfer Logic Software Defined Radio (RTL-SDR) is a low-cost software-defined radio (SDR) built around a television tuner. Group 108 at MIT Lincoln Laboratory has interest in determining the potential capabilities of SDR receivers for air surveillance. Several RTL-SDRs were put through tests to compare their performance characteristics to those of the commercial Ettus Universal Software Radio Peripheral (USRP). Prototypes were built for both a two-channel and three-channel RTL-SDR system; these systems were tested for phase offset between their receiver channels. RTL-SDRs cannot compete directly on performance with more expensive SDRs specifically built for reception, but they show good performance for their price and can be utilized in a multi-channel receiver system.
