A family of persistent ground surveillance radars made by Israel Aerospace Industries subsidiary ELTA Systems has added a foliage penetrating radar (FOPEN) to its arsenal.
Targets are detected by the analysis of the echoes returned from moving targets (doppler effect). The FOPEN radar extends the coverage of IAI Elta's ELM-2112 ground surveillance family of radars into densely vegetated, forested areas.
If you're like most of our readers, you love science and enjoy learning new things. But science is a pretty broad field, and it can be pretty daunting to approach it.
