ELVA-1 300 GHz radar developed for autonomous vehicles

ELVA-1 Low- THz (300GHz) radar in University of Birmingham.
Safety in using autonomous vehicles depends to radar ability to deliver a resolution high enough to be compatible with that of the optical image. Performance of low-THz radar, capable to deliver required resolution, is considered in this study, with the focus on reflectivities of pedestrians at frequencies within the low-THz region – 150 and 300 GHz. Backscatter returns are collected in a controlled environment at a number of frequency bands and at different aspect angles.

Penetrating Dust: our FMCW Distance Sensor Prototype Tested in the Real Field Conditions in Nickel Mine.

     The low power 10 mW, 94 GHz sensor was used. During the experiment, a laser sensor was tested side-by-side with the millimeter-wave sensor. To simulate an opaque dust cloud, a bag of cement and ore dust was dispersed in a mine tunnel using compressed air and powerful fans. A large underground vehicle, 50 m distant from the sensors was used as a target. The experiment showed that the prototype FMCW distance sensor easily penetrated the cement dust, and that the target echo was clearly visible on the data collection PC. At the same time the laser sensor lost sight of the target as soon as the dust cloud reached the sensor beam. Read more
