Standard NEBO uses about three different radar antenna in three different radar wavelengths.
(NEBO-M only has two radar... one VHF and the other UHF...)
High frequency Ka and Ku band, longer wavelength... probably about L band, and much longer wavelength where the signals are tens of metres long.
Those big tall radar arrays are the longer wavelength antenna.
Traditionally such radar were ideal for search radar... not particularly precise or sophisticated but detected incoming threats so higher frequency radars with much better positional accuracy could then be used to determine how many attackers there are and their location for fighters to intercept them and for SAMs on their flight path to activate and get ready for their approach.
Their lack of accuracy meant they were only used for detection... so everything else could be resting so when they were needed they could be ready and fresh.
Each frequency range has advantages and problems... the main problem for high frequency radars is that modern stealth aircraft are physically designed to redirect any high frequency radar wave in directions other than which from the direction they came. Longer waves are less directional and less effected by shape and bounce off the entire aircraft.
NEBO is such an effective radar system because they first of all updated all three frequencies of radar to modern AESA standards with digital computer processing power, and they use software to combine and maximise the advantages of the radars while reducing or eliminating the problems.
This means that you don't have one screen showing each of the radar returns from each radar, the computers combine the information and form a much more detailed display than any one of the radars could provide.
In terms of optical light think of it as being a telescope that includes IR sensitivity with thermal imaging... so a normal digital camera sees colours and detail and is good for identifying things, humans and objects, but it also has a thermal camera so humans... even in camo paint and ghillie suits glow with their heat signature which means a simple video processing computer can put targeting boxes around hot things and also moving things so a zoomed in digital camera can give you a close up detailed look at potential targets with the stabilisation system and camera pointing mechanism moving the camera from hotspot to hotspot and or moving targets so the operator can check if the target is something of interest like an enemy soldier, or a bird or animal or drone.
