That's an excellent question.
There are different types of radar, or at least radar processing, for different targets of interest. This is the language we use. We're tracking vessels on the water versus drones, or aircraft in the air versus persons walking out of a forest onto an open road or field.
I'm familiar with a lot of those areas. Certainly drones are an important new concern. We have good drone-detection capability to see drones carrying contraband fly out of or above those areas.
For persons, there is everything from cameras to sensors underground that can actually see and track people coming out of forested areas. That technology has been well developed. It was included in and originally part of the BITEP, which I referred to.
It's a combination of radar, counter-drone, drone-detection sensors and human-detection sensors, which are what we typically call radio frequency-based or camera-based technologies. They're readily available.
