During 2021 we will continue to support students who need to study remotely due to the ongoing impacts of COVID-19 and travel restrictions. Make sure you check the location code when selecting a unit outline or choosing your units of study in Sydney Student. Find out more about what these codes mean. Both remote and on-campus locations have the same learning activities and assessments, however teaching staff may vary. More information about face-to-face teaching and assessment arrangements for each unit will be provided on Canvas.

MECH5720: Sensors and Signals

Syllabus Summary: This course starts by providing a background to the signals and transforms required to understand modern sensors. It goes on to provide an overview of the workings of typical active sensors (Radar, Lidar and Sonar). It provides insight into basic sensing methods as well as aspects of interfacing and signal processing. It includes both background material and a number of case studies. The course covers the following topics: a) SIGNALS: Convolution, The Fourier Transform, Modulation (FM, AM, FSK, PSK etc), Frequency shifting (mixing) b) PASSIVE SENSORS: Infrared Radiometers, Imaging Infrared, Passive Microwave Imaging, Visible Imaging and Image Intensifiers c) ACTIVE SENSORS THE BASICS: Operational Principles, Time of flight (TOF) Measurement and Imaging of Radar, Lidar and Sonar, Radio Tags and Transponders, Range Tacking, Doppler Measurement, Phase Measurement d) SENSORS AND THE ENVIRONMENT: Atmospheric Effects, Target Characteristics, Clutter Characteristics, Multipath e) ACTIVE SENSORS: ADVANCED TECHNIQUES: Probability of Detection, Angle Measurement and Tracking, Combined Range/Doppler and Angle Tracking, Frequency Modulation and the Fast Fourier Transform, High Range Resolution, Wide Aperture Methods, Synthetic Aperture Methods (SAR) Objectives: The course aims to provide students with a good practical knowledge of a broad range of sensor technologies, operational principles and relevant signal processing techniques. Expected Outcomes: A good understanding of active sensors, their outputs and applicable signal processing techniques. An appreciation of the basic sensors that are available to engineers and when they should be used.

  • MATLAB tutorial: A number of hands-on tutorials will be undertaken during which the students are expected to apply and investigate what they have learned by developing models and software.
  • Quizzes: Quizzes will be held at the end of each lecture to ensure that students have understood the work covered so far.
  • Lab activities: Weekly individual on-line or face-to-face activities during which students will be required to assemble sensing, processing, and actuation hardware that illustrates some sensing and signal processing concepts.
  • Assignment: The individual design assignment will be based on ongoing work done by the students to develop ideas for a sensing device in stages throughout the first half of the semester as their knowledge and understanding of the subject develops.
  • Final exam: Open-book examination that will include a number of short-answer questions. Note that students will be required to pass the exam, to pass the course.

Detailed information for each assessment can be found on Canvas.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

Special consideration

If you experience short-term circumstances beyond your control, such as illness, injury or misadventure or if you have essential commitments which impact your preparation or performance in an assessment, you may be eligible for special consideration or special arrangements.

Academic integrity

The Current Student website provides information on academic honesty, academic dishonesty, and the resources available to all students.

The University expects students and staff to act ethically and honestly and will treat all allegations of academic dishonesty or plagiarism seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic dishonesty. If such matches indicate evidence of plagiarism or other forms of dishonesty, your teacher is required to report your work for further investigation.

Attendance and class requirements

  • Project work (own time): A design project will be undertaken by groups of students. This will take the form of research conducted by each student during the semester as their knowledge of the subject improves. Towards the end of semester individual students will compile a single design report which will be assessed by the lecturer.
  • Independent study: Depending on student competence and background, at least three hours of private study per week outside formal contact hours will be required to consolidate the work covered in class.
  • Laboratory: Student groups will assemble and measure the characteristics of various sensors. They will be provided with some Measure Foundry code, but will be expected to develop additional code. These may be on-line or face-to-face
  • Tutorial: A number of MATLAB tutorials will be undertaken, during which students are expected to develop the code to model some sensing or signal processing application.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University’s graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. assimilate information regarding the myriad of possibilities for the design of a sensor, and to convey this information to ones colleagues
  • LO2. develop skills for efficient project management in a team environment
  • LO3. integrate incomplete information and make value judgements to solve a sensing problem by using engineering "gut feel", rather than a rigorous analytical approach
  • LO4. apply specialised engineering skills (mechanical, electrical, and software) to analyse the performance of a sensor
  • LO5. understand active sensors, their outputs, and applicable signal processing techniques, and demonstrate an appreciation of the basic sensors that are available to engineers, and when they should be used
  • LO6. describe a number of sensors
  • LO7. make a distinction between sensor performance, based on simulation and measurement.

Graduate qualities
