doc.: IEEE 802.11-21/1801r2 November 2021 Agenda This presentation introduces the Imaging Radar We present the typical processing of an Imaging Radar Discuss the report options and evaluate them Submission Slide 2 Alecsander Eitan(Qualcomm))
doc.: IEEE 802.11-21/1801r2 November 2021 Imaging Radar Imaging Radar provides image of the scene The image is: 2D (Az, Range or Az, El or Range, Doppler) 3D (Az, El, Range or Az, Range, Doppler) 4D (Az, El, Range, Doppler) Typical Imaging Radar processing block diagram Doppler FFT Target Detection & Tracking ADC Correlator Az & El CFAR Notes: 2D is a two-dimensional data, 3D is a three-dimensional data and 4D is a four-dimensional data Az and El are Azimuth and Elevation CFAR is - Constant False Alarm Rate . CFAR detection refers to a common form of adaptive algorithm used in radar systems to detect target returns against a background of noise, clutter and interference) Submission Slide 3 Alecsander Eitan(Qualcomm)

doc.: IEEE 802.11-21/1801r2 November 2021 Conclusions Reporting Time-domain data is very ineffective for imaging Radar, and requires the recipient to perform processing, like AoA (which requires knowledge known only at the receiver) Reporting Unfiltered 2D/3D/4D map is very ineffective for imaging Radar. Reporting Filtered 2D/3D/4D map is practical Reporting Targets is the most efficient method Submission Slide 8 Alecsander Eitan(Qualcomm)
doc.: IEEE 802.11-21/1801r2 November 2021 SP #1 Do you agree to add the following to 11bf SFD: The 11bf amendment shall define one or more report methods for 2D, 3D and 4D filtered maps. SP results (Nov 23 2021): 8/4/21 Submission Slide 9 Alecsander Eitan(Qualcomm)
doc.: IEEE 802.11-21/1801r2 November 2021 Motion #1 Move to add the following to the TGbf SFD: The 11bf amendment shall define at least one measurement report type for 2D, 3D and 4D filtered maps, for DMG/EDMG. This measurement report type is an optional feature. Supporting 2D, 3D and 4D are each optional feature The details of the measurement report format is TBD 2D is a two-dimensional map, where the two dimensions are any from: Range, Azimuth, Elevation & Doppler. 3D is a three-dimensional map, where the three dimensions are any from: Range, Azimuth, Elevation & Doppler. 4D is a four-dimensional map, where the four dimensions are: Range, Azimuth, Elevation & Doppler.

doc.: IEEE 802.11-21/1801r2 November 2021 SP #2 Do you agree to add the following to 11bf SFD: The 11bf amendment shall define one or more report methods for targets. ( Target is a detected object. e.g. with a 3D size and specific doppler) SP results (Nov 23 2021): 8/10/16 Submission Slide 11 Alecsander Eitan(Qualcomm)
