Solar-blind ultraviolet optical system design for missile warning

Signal-to-Noise Ratio Analysis Based on Different Space Remote Sensing Instruments

“…For commonly used ICCD and ICMOS, it can be assumed that there is no gain register, so the dark current noise and readout noise do not increase proportionally in the image intensifier. Therefore, for microphoto remote sensing instruments using image intensifiers, the noise signal model can be represented by ( 24 [43][44][45]. As a result, the infrared radiation emitted by these exhaust plumes constitutes a significant portion of the overall spectral radiation from the target.…”

YOLOv5-based Passive Missile Detection using simulated Solar Blind Ultraviolet Signatures

“…These advancements are progressively establishing IR missile warning systems as the preferred option, thereby displacing ultraviolet (UV) missile warning systems from their traditional role. However, compared with IR warning technology, UV warning technology and specifically Solar Blind Ultraviolet (SBUV) band located between 240 and 290 nanometers still has many advantages such as low false alarm rate, refrigeration independence, small volume and light weight [14]- [17]. Background clutter is the biggest challenge faced by IR-based missile detection systems, especially operating close to ground surfaces, as the IR clutter from the surface of the earth is the highest and poses a serious challenge to missile identification systems [14]- [16].…”

Interface Trap Effect on the n-Channel GaN Schottky Barrier-Metal–Oxide Semiconductor Field-Effect Transistor for Ultraviolet Optoelectronic Integration

“…The ability to characterize ultraviolet (UV) emission spectra is important because it can provide important insights into the semiconductor industry, military aircraft survivability equipment, space-based communication, solar science, and even biological agents [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. Within the semiconductor industry, extreme UV (EUV) lithography technology using a wavelength of 13.5 nm has facilitated the creation of a complex integrated circuit fabrication process for the most advanced microchips (7, 5, and 3 nm modes).…”

“…Moreover, EUV detectors are the key components used for monitoring and calibrating photon beam intensity [4][5][6]. In the military field, missile warning receivers (MWRs) using UV signal detection have been studied to counter missile systems such as man-portable air defense systems (MANPADS) [8,9]. In these systems, spectra from 240 to 280 nm are applied to detect the tail flames of approaching missiles.…”
