Type 346 radar

Type 346 radar is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Type 346 radar rather than just read about it. In short: The Type 346 radar (NATO/OSD: Dragon Eye) is a naval C/S band active electronically scanned array (AESA) radar developed in the People's Republic of China by the Nanjing Research Institute of Electronics Technology. It has been an integral component of Chinese naval air defense systems since entering service in 2004 with the Type 052C destroyer, the first Chinese warships with area air defence capability.

Key takeaways

Type 346 radar belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Type 346 radar to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Type 346 radar from memory before moving on to harder problems.

Reference excerpt

The Type 346 radar (NATO/OSD: Dragon Eye) is a naval C/S band active electronically scanned array (AESA) radar developed in the People's Republic of China by the Nanjing Research Institute of Electronics Technology. It has been an integral component of Chinese naval air defense systems since entering service in 2004 with the Type 052C destroyer, the first Chinese warships with area air defence capability.

Development The Type 346 was developed by the Nanjing Research Institute of Electronics Technology; it became part of China Electronics Technology Group Corporation Glarun Group which continues to manufacture the radar. Further development may have been assisted by the examination of foreign technology; the Type 051C destroyers used 30N6EI Tombstone phased-array Flap Lid antennae from Russia, and in 2004 a prototype C band active phased-array radar and its design package were purchased from the Kvant Design Bureau of Ukraine. It is manufactured by China Electronics Technology Group Corporation.

Variants Type 346 Initial version. The arrays are covered by convex panels. It entered service with the Type 052C destroyer. Type 346A This version has a reported range of 400 km. and is covered by flat panels because of an improved liquid-cooling system. It entered service with the Type 052D destroyer. Type 346B This version uses panels that are 40% larger than the Type 346A for a reported 60% increase in range. It entered service with the Type 055 destroyer.

Worked examples

Example 1 — a first encounter with Type 346 radar

Start with the simplest possible case. Write down what Type 346 radar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Type 346 radar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Type 346 radar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Type 346 radar

In research: Type 346 radar appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Type 346 radar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Type 346 radar is common in secondary-school and first-year university syllabi. It links to neighbouring topics Military equipment introduced in the 2000s, Military radars of China, Nanjing Research Institute of Electronics Technology, so understanding it makes those chapters shorter.
In everyday life: Look for Type 346 radar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Type 346 radar in simple terms?

Why does Type 346 radar matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Type 346 radar?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
