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

“…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]. However, it is critical to acknowledge that the SBUV band experiences a significant reduction in background clutter.…”

“…Predicting the trajectory especially when the objects are moving at speeds above Mach 2 is even more complex because the high speeds make it difficult for sensors as well as detection algorithms to accurately track the objects, and there may be issues with motion blur, noise, and other factors that can affect the accuracy of the data. In [16], a multi-band SBUV early warning system investigation was conducted for ballistic missiles. The design of a geostationary orbit space-based ultraviolet early warning system is also simulated.…”
