Type 343 Radar

Type 343 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 343 Radar rather than just read about it. In short: Type 343 radar (Chinese: 343型雷达) is a Chinese fire control radar installed on Type 051 destroyer, and has been since retired from active service. Type 343 radar is the first generation Chinese fire control radar for large caliber guns, with development begun in 1968, with 720th Research Institute assigned as the develop in October of the same year.

Key takeaways

Type 343 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 343 Radar to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Type 343 Radar from memory before moving on to harder problems.

Reference excerpt

Type 343 radar (Chinese: 343型雷达) is a Chinese fire control radar installed on Type 051 destroyer, and has been since retired from active service. Type 343 radar is the first generation Chinese fire control radar for large caliber guns, with development begun in 1968, with 720th Research Institute assigned as the develop in October of the same year. Sea trials begun in July 1970 and design completed in 1976, with state certification received in 1979. A total of 12 sets were produced, with first five built by 720th Institute, and production subsequently transferred to Plant 410 in Guizhou in 1982. The radar operates in two bands, X-band is usually used, with Ku-band as backup. The radar can detect and track medium-sized surface target around 30 and 20 km away respectively. Type 343 is a 2-D air search radar with MTBF of 40 hours, and in addition to control guns, it is also used for anti-ship missile fire control. As a 2-D air search radar, Type 343 can only provide bearing and range, and to provide altitude information on the target, a large optical ranging set is needed, which requires an operator. Therefore, an operator's cupola is attached to the radar, immediately behind the antenna. An improved version Type 343-Gai (改), has the operator cupola deleted and the bulky complex optical ranging set replaced by a compact, but far more capable electro-optical sensor (EO) that is only a tiny fraction size of the original equipment it replaced. As more advanced radars available, Type 343 has been phased from active service in Chinese navy.

Worked examples

Example 1 — a first encounter with Type 343 Radar

Start with the simplest possible case. Write down what Type 343 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 343 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 343 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 343 Radar

In research: Type 343 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 343 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 343 Radar is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese military stubs, Military equipment introduced in the 1970s, Sea radars, so understanding it makes those chapters shorter.
In everyday life: Look for Type 343 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.
