|DLW002 CONOPS diagram|
DWL002 Emitter Locating System (ELS) is a big evolutionary leap beyond the original Russian Tamara and improved Vera ELS systems.
The key feature is the addition of a second receiver. This provides the DWL002 ELS with two important advantages.
Firstly, a single DWL002 unit can use triangulation to pinpoint the exact location of an enemy aircraft. In contrast, a single Russian receiver can only identify the direction but not the precise location of an enemy aircraft.
Secondly, DWL002 has two receivers that permit interferometry. Though this does not increase the range, the resolution/sensitivity is equivalent to a receiver that is almost the length of the mast.
I have included two citations below to show that China has researched interferometry, including X-band radar.
If two Chinese DWL002 are linked via tight wireless transmission or fiber-optic cables to create a super-interferometer, the resolution would be incredible. If multiple DWL002 are interconnected and the data is processed by computers, the result is an interferometer of unimaginable sensitivity.
