A Broadband Multistatic Radar for Trajectory Identification of Multiple Small Caliber Targets

In recent years, the use of radar for remote sensing has scaled from the detection and tracking of large meter-scale feature sizes to the identification of finer objects and movements. Of particular interest in defense applications is the identification of the trajectories of small caliber projectiles during flight. We present a broadband multistatic radar system for the identification of multiple target trajectories where velocities exceed 300 ms

. Our radar system is demonstrated at an outdoor firing range in 9-mm caliber live fire experiments. Results indicate that this radar is a promising system for the identification of multiple small, fast-moving object trajectories.
