Foliage creates a barrier that can reflect signals and prevent them from reaching the objects and terrain below. FOPEN is performed using low-frequency radar systems (see SAR) whose long wavelength signals naturally penetrate foliage. Optical and infrared sensors do not penetrate through foliage and can even be reflected by other, less dense barriers including clouds and smoke.
Low-frequency radar systems can produce a variety of data products through foliage. For example, SAR imaging with low-frequency radar allows manmade objects, such as buildings and vehicles, to be directly detected through foliage. Additionally, significant changes beneath foliage can be detected by using the CCD process. (See CCD)
Using FOPEN and combining it with other ISR solutions allows IMSAR systems to perform multiple applications in a variety of industries. Typical uses for IMSAR’s ISR solutions can include:
IMSAR systems that are capable of performing FOPEN are available in a variety of configurations that are designed for easy integration onto manned or unmanned aircraft.
