Radar Theory and ATIcourses Technical Training

This is an interesting link about radar theory. ATIcourses provide many courses related to practical applications of radar to defense for airborne, ship and ground-based radar.

This is an interesting link about radar theory. ATIcourses provide many courses related to practical applications of radar to defense for airborne, ship and ground-based radar.

The Radar Theory Pages are taken from the R.A.F Standard Technical Training Notes (STTN) AP3302 Part 3 (2nd edition), the manual used in Royal Air Force Apprentice training from the mid 1960’s to the early 1970’s. The original document is quite out of date now, some of the symbols used are no longer in use for example and valves are mostly a distant memory. Eventually I hope to add appendices that reflect current practice but for the mean time I want to recreate the feel of the original manual.

I have endeavored to recreate the layout and page numbering of the original manual in order to retain the “feel” of the original. To support this “feel” I have placed buttons at the bottom of each page that allow the user to got to the next page, the previous page or return to the top of the current page. Therefore this section works like a book, just turn the page when you reach the bottom. To facilitate navigation I will include the contents and index pages complete with hypertext links eventually, in the mean time you will find links to the various sections on the left hand panel
The original document contains over 650 pages. This represents a lot of work with the PC and the scanner in order to get it all into HTML. I use Textbridge to scan the text and Paintshop Pro and MS Photoeditor to scan and manipulate the images. Please be patient, I’m sure I’ll get all 650 pages onto the network eventually!

These pages are not intended to be a treatise on radar techniques! It is more like a dictionary than an encyclopedia; acronyms will be spelt out, techniques and terms will be briefly explained. For more information get the books out and RTFM!

Ace d’ Base At the top of the profession, no one on the site can better this fellow!
AFC Automatic Frequency Control
Agile A radar system capable of rapidly jumping from one frequency to another. Used to defeat spot jamming.
Airway Controlled airspace in the form of a road in the sky. In the UK the airway is usually identified by a colour and a number ie Red 01, Green 15 etc. (A rich source of targets)
AMES Air Ministry Experimental Station, as in AMES Type 80 and so on.
AN/FPS-6 US built height finding radar. AKA “Nodding Horror”
AN/xxx-xx US military equipment designation – see next glossary page for full details
Ana-Prop Anomalous Propagation of radar signals that causes ground returns and targets to be seen out to greater than normal distances – or not at all!. Often caused by refraction of the signal in the atmosphere in regions of high pressure
Angels Height in thousands of feet, ie Angels 15 = 15,000 feet. (This term was also used in the early days of radar to describe returns caused by large flocks of birds. In those days they didn’t know what caused these returns, so if they weren’t aircraft they must be angels!)
