Integrating Multiband Active and Passive Radar for Enhanced Situational Awareness

This article presents the data fusion results of integrating several multiband active and passive radar sensors for enhanced situational awareness. The two sensor technologies come with partially complementary properties, thus a suitable mix provides improved performance in a couple of situations of operational interest. The presented results have been obtained during a trial measurement campaign of the NATO Science and Technology Organization, which took place on 3–13 September 2019, in Poland. Held under the code name Active Passive Radar Trials—Ground-based, Airborne, Sea-borne (APART-GAS), this trial campaign was attended by over 70 participants from 10 countries. It covered many new predefined military scenarios tested in real time. This article's results verify and validate the Deployable Multiband Passive Active Radars (DMPAR) concept developed during previous work by various NATO research groups.
