Dual-Band Aerodynamic Electro-Optical Seeker

In implementing an electro-optic (EO) seeker, the selection of a waveband or wavebands is the major decision for the system design. The visible and near-infrared wavebands work well in the daytime when the atmosphere is clear, but passive imaging systems in these bands are not useful at night, and they are susceptible to scattering in fog, smoke, and dusty environments. The mid-wave infrared (MWIR: 3-5 µm) and long-wave infrared (LWIR: 8-12 µm) wavebands each offer unique advantages, but do not address all conditions encountered on the modern battlefield. To maximize the detection range, to meet cost goals, and to minimize size, weight, and power (SWaP), the Optimax team has chosen to pursue a dual-band solution encompassing sub-bands within both the MWIR and LWIR. This dual-band solution will be paired with a conformal aerodynamic optical window, enabling enhanced aerodynamic performance and increased field of regard when compared to traditional spherical components. Together, this system will equip fast moving projectiles with the capabilities for precise detection and discrimination of tactical surface targets.
