Holographic radar has tracked supersonic 5 inch shells

Groundbreaking holographic radar pinpoints impact of rapid shell fire for US Department of Defense. Following just 14 months of development, Cambridge Consultants unveiled the industry’s first holographic radar scoring system, the Land and Surface Target Scorer (LSTS).

Cambridge Consultants, a leading technology design and development firm, has successfully carried out trials tracking 5 inch shells travelling at over 1,000 miles per hour for the US Department of Defense (DoD). The groundbreaking radar developed specifically for this task was able to measure the trajectory and burst points of shells fired from a naval gun at a rate of one every three seconds - the first time radar has been used this way.

Installed on high-speed land or sea-surface target vehicles, the system uses receiver array panels combined with high-speed signal processing to detect and track small projectiles in the presence of very large radar clutter, such as that experienced on moving land and sea surface targets. During trials at the Naval Surface Warfare Center, Dahlgren VA, the system successfully detected, tracked and located the point of impact of inert 5 inch projectiles, and was also able to plot the burst point of a high explosive round. Observers were able to see the results in near real-time on a laptop.




During these trials we were able to produce raw data plots immediately and full trajectory reconstructions in just 15 minutes, under the scrutiny of our customer.”

The demonstration test took place with the radar system mounted on a tethered pontoon to prove its detection and tracking capabilities over a zone within the specified 360 degree, 1,000 foot coverage. The demonstration team then conducted a rapid-fire test, during which all rounds were tracked through to impact on the water.
