Phased Arrays

Our detection pipeline begins with a high-performance 150mm Cassegrain telescope, paired with a state-of-the-art 135fps sCMOS sensor. This optical assembly is specifically optimized for the challenging LEO environment, where high-velocity debris creates significant motion blur.

High fidelity integration

At short ranges, Cassiopeia’s Phased Array Radar provides rapid, high-resolution debris tracking while simultaneously supporting satellite communications. The system is able to achieve near-space resolution across a constellation-without saturating communication bandwidth-by electronically steering multiple radar beams and transmitting only compressed orbital state vectors.

Precise Electronic Beam Control

Our terminal tracking phase utilizes a phased array comprising 288 elements, with its defining advantage being its independent beam control, which leverages electronic steering to manipulate the phase of each element without physical . This ability allows the array to instantly switch between multiple debris targets or compensate for satellite jitter, maintaining a "hard lock" even during complex maneuvers. By providing direct Doppler velocity measurements and high-rate angular updates, the phased array serves as the definitive validator for the orbital models initiated by our optical sensors.
