Radar Research and Development Establishment

Radar Research and Development Establishment is a engineering 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 Radar Research and Development Establishment rather than just read about it. In short: The Radar Research and Development Establishment, RRDE for short, was a civilian research organization run by the United Kingdom's Ministry of Supply that primarily studied the development of radar for British Army use. The group traces its history to the Searchlight Experimental Establishment which moved to RAF Biggin Hill in 1924, and the "Army Cell" operating at Bawdsey Manor researching radar beside their Air Mi…

Key takeaways

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

Reference excerpt

The Radar Research and Development Establishment, RRDE for short, was a civilian research organization run by the United Kingdom's Ministry of Supply that primarily studied the development of radar for British Army use. The group traces its history to the Searchlight Experimental Establishment which moved to RAF Biggin Hill in 1924, and the "Army Cell" operating at Bawdsey Manor researching radar beside their Air Ministry counterparts. In 1941 the Army groups merged and moved to Christchurch, Dorset and were renamed the Air Defence Research and Development Establishment. In May 1942 the group moved again, this time to an inland location at Malvern, Worcestershire, and were once again renamed to become the RRDE. Their Air Ministry counterparts, who had also moved to the Dorset area and been renamed the Telecommunications Research Establishment (TRE), joined them in Malvern over the next few months. The RRDE retained their name until 1953 when they merged with the TRE to form the unified Radar Research Establishment. The RRE was renamed in 1957 by Elizabeth II to become the Royal Radar Establishment.

Worked examples

Example 1 — a first encounter with Radar Research and Development Establishment

Start with the simplest possible case. Write down what Radar Research and Development Establishment claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Radar Research and Development Establishment 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 Radar Research and Development Establishment 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 Radar Research and Development Establishment

In research: Radar Research and Development Establishment appears in engineering 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 Radar Research and Development Establishment 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: Radar Research and Development Establishment is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century military history of the United Kingdom, Buildings and structures in Malvern, Worcestershire, History of telecommunications in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life: Look for Radar Research and Development Establishment 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.
