DST Group Radar Technology

For: Year 11 and 12 Physics Students

 Description

This program has been developed in collaboration with the Defence Science and Technology (DST) Group to demonstrate applications of radar technology.  Students use an audio radar as a learning tool in an experimental workshop looking at the radar concepts of reflection and Doppler shift.

The program links with the ‘Waves’ section of the SACE Stage 1 Physics curriculum. Links to the ‘Energy and Momentum’ section of the SACE Stage 1 Physics curriculum are also included.

Students work through two procedures during the session. The first procedure uses reflection to determine the distance of an object and the speed of sound in air, while the second uses Doppler shift to determine the speed of an object.

What will Students do?

Students:

  • Learn about the development of radar in the Australian defence industry.
  • Use a pulse emitting audio radar signal to collect data which, when graphically analysed, enables the determination of the speed of sound through air.
  • Use continuous wave radar to measure the Doppler shift of a sound wave that reflects from a swinging pendulum, and determine the speed of the pendulum using graphical and mathematical analysis.
  • Analyse the results through calculation of percentage error and discussion of random and systematic errors

Conditions

  • As this program is a practical activity, students and accompanying adults will be required to wear closed in shoes and appropriate dress.
  • Teachers will receive confirmation of booking and pre-visit information.
