Abstract
Widespread availability of long-term evolution (LTE) signals makes them potential for use in passive bistatic radar (PBR) applications. However, their utility in such applications is yet to be fully explored. This research focuses on the key LTE signal attributes, such as modulation schemes and bandwidth, and their effect on PBR application. Space-time adaptive processing (STAP) concepts, both full-dimension (FD-STAP) and reduced-dimension (RD-STAP), were employed to evaluate and compare the effects of varying these signal attributes, in terms of signal to interference-plus-noise ratio (SINR) metrics. Simulation results indicate that decreasing LTE signal's bandwidth and increasing its bitrate will worsen both SINR <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</sub> and SINR <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L,o</sub> . This trend remained valid irrespective of the type of STAP algorithm used.
