Type 514 Radar

Type 514 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 514 Radar rather than just read about it. In short: Type 514 radar is a Chinese 2-D air search radar in service with both Chinese Ground Force (PLAGF) and Chinese navy (PLAN). Type 514 radar is a land based, mobile 2-D air defense radar developed from earlier Type 513.

Key takeaways

Type 514 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 514 Radar to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Type 514 Radar from memory before moving on to harder problems.

Reference excerpt

Type 514 radar is a Chinese 2-D air search radar in service with both Chinese Ground Force (PLAGF) and Chinese navy (PLAN). Type 514 radar is a land based, mobile 2-D air defense radar developed from earlier Type 513. The radar has been retired from active service, being replaced by more advanced radars such as Type 354 on PLAN destroyers and frigates. When China built/converted its first generation frigates Type 6601 in the 1960s, domestic Chinese diesel engines to meet military standard were not ready, so civilian diesel engines had to be used, but civilian diesel engines were heavier and bulkier, especially in terms of height. Compounded with the smaller size of the frigate, the land-based Type 515 radar adopted for naval use onboard Type 051 destroyers was too big to be installed on smaller frigates, so an alternative had to be sought. Type 514 mobile 2-D air search radar already in service with PLANAF was more compact than Type 515, and was thus selected as an emergence stopgap measure until more advanced radar became available for Chinese frigates urgently needed air defense radars at the time. Development of the naval version of Type 514 radar begun in September 1964, and because it was based on the matured land-based version, development was very smooth and completed in the first half of the following year. In July 1965, the radar entered series production and delivered to PLAN. However, Type 514 was only aboard these early Chinese frigates for a very short period of time, when Type 354 entered series production in April 1974, it soon replaced all Type 514 radars on Chinese ships.

Worked examples

Example 1 — a first encounter with Type 514 Radar

Start with the simplest possible case. Write down what Type 514 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 514 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 514 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 514 Radar

In research: Type 514 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 514 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 514 Radar is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese military stubs, Military radars of China, Sea radars, so understanding it makes those chapters shorter.
In everyday life: Look for Type 514 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.
