Cellular Satellites: Joint Communications with Integrated Acquisition

It’s a familiar image: a soldier crouching with a radio next to a spidery antenna pointing skyward to reach a distant satellite. But that view of military communications is on the verge of change, being replaced by troops rapidly exchanging data while moving seamlessly around the battle space.

Virtual Flight Testing of Radar System Performance

Flight testing is the ultimate way to evaluate the performance of a radar system. During the actual aircraft flight, data such as Probability of Detection, Signal Strength, and clutter might be gathered. While effective, this approach does pose a number of challenges. The operational cost of flight testing a radar system using real aircraft can be over $100,000 per hour. Additionally, the results from one flight to the next are not repeatable. Each flight is slightly different, and getting enough flights in to be statistically significant is simply too cost-prohibitive.
