Radar-image shaper for radar-based applications

A method implemented by an electronic device that includes a radar system, the method comprising:

• providing, by the radar system, a radar field;
• sensing, by the radar system, reflections from an object in the radar field;
• analyzing the reflections from the object in the radar field;
• providing, based on the analysis of the reflections, radar data;
• detecting, based on a first subset of the radar data, a radar signature of a radar-image shaper that is attached to the object in the radar field;
• comparing the detected radar signature to a benchmark radar signature, the benchmark radar signature corresponding to a characteristic disposition of the radar-image shaper, the comparison comprising:
• determining features of the radar-image shaper based on the first subset of the radar data;
• and
• analyzing the determined features to determine a match to known features of the benchmark radar signature;
• determining, based on the comparison, that the detected radar signature matches the benchmark radar signature;
• and
• responsive to determining that the detected radar signature matches the benchmark radar signature, determining a characteristic disposition of the object in the radar field, based on the characteristic disposition of the radar-image shaper that corresponds to the matched benchmark radar signature.

A stylus, comprising:

• a stylus housing;
• and
• a radar-image shaper integrated with the stylus housing, the radar-image shaper configured to provide a radar signature that is detectable by a radar system, the radar signature effective to enable the radar system to determine a characteristic disposition of the housing, the determination of the characteristic disposition of the housing comprising:
• detecting the radar signature of the radar-image shaper;
• comparing the detected radar signature to a benchmark radar signature, the benchmark radar signature corresponding to a characteristic disposition of the radar-image shaper, the comparison comprising:
• determining features of the radar-image shaper, based on the radar signature;
• and
• analyzing the determined features to determine a match to known features of the benchmark radar signature;
• determining, based on the comparison, that the detected radar signature matches the benchmark radar signature;
• and
• responsive to determining that the detected radar signature matches the benchmark radar signature, determining a characteristic disposition of the housing based on the characteristic disposition of the radar-image shaper that corresponds to the matched benchmark radar signature.
