Arrow В Арктике развернут загоризонтные РЛС "Подсолнух" Ono što je zaniljivo u tekstu je dato u citatu. Citat:Всепогодная загоризонтная радиолокационная станция ближнего действия "Подсолнух" разработана Научно-исследовательским институтом дальней радиосвязи, входящем в состав концерна "РТИ". Она предназначена для обнаружения надводных и воздушных целей на расстоянии до 450 км. Применяется для всепогодного непрерывного круглосуточного контроля надводной и воздушной обстановки в пределах 200-мильной экономической зоны Российской Федерации.
Главной особенностью РЛС "Подсолнух" является ее загоризонтный обзор - станция способна обнаруживать морские надводные и воздушные объекты на разных высотах как в пределах прямой видимости, так и за линией горизонта. РЛС "Подсолнух" позволяет в автоматическом режиме одновременно или последовательно обнаружить, сопровождать и классифицировать до 300 морских и 100 воздушных объектов, определять их координаты и выдавать по ним целеуказания комплексам и системам вооружения кораблей и средств противовоздушной обороны.
Znači, pristojan domet za otkrivanje površinskih i vazdušnih ciljeva i dobri kapaciteti praćenja i klasifikacije ciljeva .

New Radars, IRST Strengthen Stealth-Detection Claims

Citat:VHF AESA technology has entered production as part of the 55Zh6M Nebo-M multiband radar complex, which passed State tests in 2011 and is in production for Russian air defense forces against a 100-system order. The Nebo-M includes three truck-mounted radar systems, all of them -AESAs: the VHF RLM-M, the RLM-D in L-band (UHF) and the S/X-band RLM-S. (Russian documentation describes them as metric, decimetric and centimetric—that is, each differs from the next by an order of magnitude in frequency.) Each of the radars is equipped with the Orientir location system, comprising three Glonass satellite navigation receivers on a fixed frame, and they are connected via wireless or cable datalink to a ground control vehicle.

One of the classic drawbacks of VHF is slow scan rate. With the RLM-M, electronic scanning is superimposed on mechanical scanning. The radar can scan a 120-deg. sector mechanically, maintaining continuous track through all but the outer 15-deg. sectors. Within the scan area, the scan is virtually instantaneous, allowing energy to be focused on any possible target. It retains the basic advantages of VHF: NNIRT says that the Chinese DF-15 short-range ballistic missile has a 0.002 m2 RCS in X-band, but is 0.6 m2 in VHF.

The principle behind Nebo-M is the fusion of data from the three radars to create a robust kill chain. The VHF system performs initial detection and cues the UHF radar, which in turn can cue the X-band RLM-S. The Orientir system provides accurate azimuth data (which Glonass/GPS on its own does not support), and makes it possible for the three signals to be combined into a single target picture.

The higher-frequency radars are more accurate than VHF, and can concentrate energy on a target to make successful detection and tracking more likely. Using “stop and stare” modes, where the antenna rotation stops and the radar scans electronically over a 90-deg. sector, puts four times as much energy on target as continuous rotation and increases range by 40%.

Meni je interesantan i ovaj detalj u napred pomenutom tekstu:
Citat:Boeing has promoted the EA-18G Growler’s ability to jam in the VHF band, which is built into the current ALQ-99 low-band pod configuration (the most modern part of the system) and the planned Increment 2 of the Next Generation Jammer system. Increment 2 will likely comprise an upgrade to the current pod—the best solution to emerge from an analysis of alternatives conducted in 2012. A contract should be issued in 2017 with initial operational capability in 2024.

Citat:Радиолокационный комплекс "Небо-М" тоже будут производить на новом заводе "Алмаз-Антей" в Нижнем Новгороде .

Kako bi se taj sistem NeboM poredio sa S400?

Sta da se poredi ? To je osmatracki radar, moze biti deo sistema S-300/400 ako imas para... Nebo M je najnoviji i kombinuje sve opsege prethodnika, VHF kao kod Nebo SVU, L opseg kao kod Protivnika i S i X kao kod Game S1, ako na takvo poredjenje mislis.
