Euroradar CAPTOR

Euroradar CAPTOR 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 Euroradar CAPTOR rather than just read about it. In short: The Euroradar Captor is a next-generation mechanical multi-mode Pulse Doppler Radar designed for the Eurofighter Typhoon. Development of Captor led to the AMSAR (Airborne Multirole Solid State Active Array Radar) project which eventually produced the CAESAR (Captor Active Electronically Scanned Array Radar), now known as Captor-E.

Key takeaways

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

Reference excerpt

The Euroradar Captor is a next-generation mechanical multi-mode Pulse Doppler Radar designed for the Eurofighter Typhoon. Development of Captor led to the AMSAR (Airborne Multirole Solid State Active Array Radar) project which eventually produced the CAESAR (Captor Active Electronically Scanned Array Radar), now known as Captor-E.

Development

Early development In June 1985, discussions began amongst various corporations to sound out the possibility of cooperation on the radar for the EFA, the project that would later become the Eurofighter. The United Kingdom chose Ferranti as the leading contract partner, Germany AEG-Telefunken and Italy FIAR. Spain, which had no radar experience, played only a minor role, later selecting Eesa as the main contractor. Towards the end of June 1985, a memorandum of understanding was signed between the UK, Germany, France, Italy and Spain to develop a joint radar for the EFA. France had already indicated at the time that it intended to withdraw from the programme. The French company Thomson-CSF was thus faced with a dilemma, as it would have liked to participate in an EFA radar. Therefore, in 1987, Thomson-CSF negotiated with Ferranti to secure a share of the work. Specifically, the travelling-wave tube was to be supplied which was possibly the same one that was to be used in the Rafale. In March 1987, Ferranti and AEG sent their offers to Eurofighter GmbH. Ferranti presented its ECR-90, based on the Blue Vixen, as early as 1986, while AEG offered the MSD-2000 "Emerald", which was based on the AN/APG-65. Ferranti's main argument was that a European fighter aircraft should also be equipped with a European radar. Ferranti had already been working with Thompson-CSF, Inisel and FIAR on the development of the radar since 1983. France withdrew with Thompson-CSF in June 1985, followed a year later by AEG. AEG wanted to offer a system based on the APG-65, as the company already had the production licence for this. There was still speculation as to whether Thorn-EMI would offer the AN/APG-68, but this did not end up happening. Both bidders submitted two-part offers: one that fully met the tender requirements and a reduced low-cost variant. Ferranti and FIAR offered the ECR-90 and the Super Vixen, AEG and GEC Marconi the MSD-2000 and the APG-65, but both high-tech offers were too expensive and the low-cost alternatives were deemed insufficient. As a result, a new tender was launched. This time, the performance requirements were slimmed down and the manufacturers were also asked how the costs could be reduced. The requirements were also less stringent in order to fuel the inventive spirit of the engineers. The two new tenders were submitted in February 1988:

Worked examples

Example 1 — a first encounter with Euroradar CAPTOR

Start with the simplest possible case. Write down what Euroradar CAPTOR 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 Euroradar CAPTOR 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 Euroradar CAPTOR 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 Euroradar CAPTOR

In research: Euroradar CAPTOR 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 Euroradar CAPTOR 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: Euroradar CAPTOR is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aircraft radars, Ferranti, Military radars, so understanding it makes those chapters shorter.
In everyday life: Look for Euroradar CAPTOR 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.
