Performance analysis for T-RN multistatic radar system
Multistatic radar system has a great potential for human detection and tracking for its fine localization precision, wide coverage and good observability. T-RN (one transmitting antenna and N receiving antennas) radar system is the most popular multistatic radar structure. In this paper, the localization performance of T-RN radar is evaluated using Cramér-Rao lower bound (CRLB). The localization precision of different radar topology types and different numbers of receiving antennas are compared. The localization performance is also evaluated by experimental data. The results reveal that more separated receiving antenna configurations and more numbers of receiving antennas have better localization precision.
