Course Code:
AHPF0040
Course Aims:
This largely practical course is designed to train Engineers in the principles of Primary and Secondary Radar and its use in Air Traffic Operations
Course Description:
The concepts of Air Traffic Control, Primary and Secondary Surveillance Radar are described. These concepts are applied to the various types of radar: Airfield Surface Movement Indicators; Airfield Surveillance Radars; Long Range Area Surveillance Radars and Secondary Surveillance Radars.
A variety of microwave devices used in radar are discussed, e.g. magnetrons, klystrons and travelling wave tubes. Further topics include aerial types, Moving Target Indicators, Moving Target Detectors and Plot Extraction techniques, PRFD, Pulse Compression and Thresholding.
Later sections introduce displays and typical methods of radar site data handling and transmission. Radiation hazards and measuring are covered.
The content of the course may vary to reflect changes and new techniques as they are introduced.
This is a very hands on course with many practical sessions.
Training Objectives:
At the end of the course, with the aid of relevant documentation, the student will be able to:
- Name the Radar Parameters of a pulsed, primary system and describe how they effect the radar's performance including reference to the Radar Equation, Pulse Width, Transmitter Power, Pulse Repetition Frequency (PRF), pulse stagger, choice of frequency, turning rate, aerial beam width, range and bearing discrimination and their relationship to Long, Medium and Short Range Primary Radars
- Describe how a Primary radar transmitter functions including the coherence / non-coherence with reference to Magnetrons, Klystrons and Travelling Wave Tubes (TWT). Pulse compression techniques
- Describe how a Primary radar receiver functions including bandwidth, effects of noise, Transmitter/Receiver switching, circular polarisation and swept gain
- Describe Primary Video Processing including Moving Target Indication (MTI), Moving Target Detection (MTD), clutter maps and Range Azimuth Gating (RAG)
- Describe the principles behind the operation of Secondary Surveillance Radar (SSR) including pulse formats, SPI pulse, emergency codes, phantoms, FRUIT, ring around, reflections, multi-path, transponders, aerial patterns, Receiver Side Lobe Suppression (RSLS) and sliding window techniques
- Describe the principles and advantages of Monopulse Radar including Sum and Difference patterns, calculation of Off Boresight Angle (OBA) and Mode S
- 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 to block diagram level the functions of Radar Data Processing Systems using PRDS and NODE-L as examples
