- 17. Using Real and Practical-Oriented Training Aids in Radar Technology Training Course Delivery Methods in Radar Training
- 18. Course Delivery Methods • Radar trainings are taught based on reference books and published papers • Lectures and tutorials • Practical trainings are conducted using simulations, mock ups and/or demonstrations • Radar specialists enter the field with little or no hands-on experience • OJT is almost compulsory • Leads to inconsistency in the knowledge acquired by various radar specialists
- 19. Course Delivery Methods • Practical training occupies the lowest level of Edgar Dale Model
- 20. Using Real and Practical-Oriented Training Aids in Radar Technology Training A Typical Radar System
- 21. • Same antenna is used to transmit and receive is used monostatic radar system (most applications) Scan Pattern Generator Antenna Duplexer Waveform Generator Transmitter Receiver Signal Processor Data Extractor Data Processor Radar Display A Simplified Pulsed Radar Block diagram TX RX
- 22. • Complex and is made up of specialised fields – RF, microwave and antenna – propagation and waves – mechanical – computer – coding and information theory – estimation and optimization • Important to have effective radar courses that are designed to cover – adequate theoretical topics – suitable practical components A Simplified Pulsed Radar Block diagram
- 23. Raytheon Pathfinder MK2 Antenna Platform Transceiver Platform Equipment Room The antenna can be 12’ or 18’ CP or LP slotted wavegude array. (DETECTION) The pedestal turns the antenna at 20 rpm. The waveguide links the antenna and MTR where RF propagates. The MTR Down Unit consists of the controller PCB and Power PCB, Magnetron, Transmitter and Receiver. (SIGNAL PROCESSING) The uplink sends the control and command information to the MTR. The Composite downlink sends the Sync, Azimuth, Video and status to the Processors. The display consists of all the control inputs and PPI display. It also holds the processor PCBs. (DATA EXTRACTION, TRACKING & ARPA FUNCTIONS) Interfaces to other navigational equipment and radar.
- 24. Terma Scanter Radar System • Dual-Transceiver Configuration The antenna can be 18’ or 21’ CP or HP slotted wavegude array. (DETECTION) The pedestal turns the antenna from 0 to 60 rpm, programmable.. The waveguide links the antenna and Transceiver. The pedestal sends encoder, gear box sensor data to transceiver. The transceiver houses the central processor, plot extraction and tracking processor (optional), transmitter and receiver.
- 25. SkyRadar System • A Typical Training Radar System
- 26. Using Real and Practical-Oriented Training Aids in Radar Technology Training Practical Trainings in Radar Courses
- 27. • University Modules – Largely theoretical with the use of mathematical tool such as Scilab to perform complex computations • Professional Short Courses – Largely theoretical, with worked examples using mathematical tools and demonstrations – Specifically, there is 1 practical-based course that requires design and building of a simple radar system (Advanced) • Final Year Projects/Dissertation – Design and building of radar systems – Simulations and analysis of radar systems Practical Trainings in Radar Courses
- 28. • System Courses – manufacturer-specific for maintenance specialists and operators – courses cover radar theories used in the system and practical skills to carry out maintenance and operations • On-The-Job – trainees learn and work concurrently under supervision demanded by training command – manufacturer specified – usually not focused due to ad-hoc deployment and secondary tasks Practical Trainings in Radar Courses
- 29. • Mandated Courses – required by authorities such as ICAO, IMO – job functions oriented – usually crews and operations staff such as ATC Controllers, VTS Operators, .... – practical oriented with adequate theories to explain the practical actions or executions on simulators Practical Trainings in Radar Courses

I feel more confident to handle actual radar after I pass out from the school...” “... can understand the complex MTI signals better ...” “... it is easy to understand and use the system ...” “... I can relate the theory to real system with what I see and measure now ...” • Instructors' Comments “... the radar trainer can be used in both classroom and outdoor for different experiements... ” “... the laboratory sheets provided are helpful ...” “... I can explain difficult concepts better ...” Case Study
