MESA accomplishes its breakthrough by fundamentally changing the way the radar antenna array interacts with the source signal to electronically steer the radar beam. In traditional passive and active electronically scanned phased arrays (PESA and AESA), discrete phase shifters embedded in the antenna control the beam direction. MESA, in stark contrast, does not require phase shifters at the antenna elements. In fact, MESA can steer perfectly without a single phase shifter. Eliminating phase shifters dramatically reduces system complexity, eliminates primary sources of power loss, and simplifies waste-heat dissipation. MESA’s unique approach nets tremendous savings in cost, size, weight and power (C-SWAP) over traditional arrays. MESA supports all radar methodologies including FMCW and Pulse Doppler and extends across the entire radar frequency spectrum from L to W band.
