Minimum detectable velocity evaluation of bistatic radar and its relevance for ground target tracking

This paper investigates the characteristics of the minimum detectable velocity (MDV) in the case of bistatic transmitter and receiver configurations and its impact on the tracking of ground targets with airborne ground moving target indication (GMTI) radar. Based on different simulation scenarios, it is demonstrated that, in contrast to a monostatic configuration with sideways-looking radar, the MDV is not constant in general. Exploiting this knowledge in a tracking filter leads to a strongly improved performance.
