Course Description:
To train Engineers in the principles of Primary and Secondary Radar and its use in Air Traffic Operations.
Training Objectives:
At the end of the course, with the aid of relevant documentation, the student will be able to:-
- Describe the factors affecting the performance of a pulsed, primary radar system with reference to the, pulse width, transmitter power, pulse repetition frequency (PRF), choice of frequency, turning rate, aerial beam width, range and angular resolution and their relationship to long, medium and short range primary radars.
- Describe the relationship between power and range with reference to the radar equation.
- Describe how a primary radar transmitter functions including coherence / non-coherence with reference to magnetrons, klystrons and travelling wave tubes (TWT).
- Describe the principles of pulse compression using surface acoustic wave (SAW) devices.
- Describe how a primary radar receiver functions including bandwidth, effects of noise, Transmitter/Receiver switching, circular polarisation and sensitivity time control.
- Describe primary video processing including Moving Target Indication (MTI), Moving Target Detection (MTD), clutter maps and video gating.
- Describe the principles behind the operation of secondary surveillance radar (SSR) including pulse formats, SPI pulse, emergency codes, phantoms, FRUIT, ring around, multi-path, transponders, aerial patterns, side lobe suppression. Reference will be made to ICAO annex 10 where appropriate.
- Describe the principles of plot extraction / combination / assigning and formats of digital transmission to air traffic control centres (ATCCs) in CAA , RDIF , and Asterix formats.
- Describe the principles and advantages of monopulse SSR (MSSR) including sum and difference patterns, calculation of off boresight angle (OBA).
- Describe the principles of SSR Mode-S including interrogation structure, reply structure, message formats and TCAS applications with reference to ICAO annex 10 as required.
