Electronic Devices with Non-Static Object Detection

A method of operating an electronic device, the method comprising:

• transmitting, using a signal generator and an antenna, radio-frequency signals;
• measuring, using a voltage standing wave ratio (VSWR) sensor communicably coupled to the antenna, VSWR values based the radio-frequency signals;
• detecting, using one or more processors, a removable case based on the VSWR values;
• receiving, using radar circuitry, a radar signal;
• detecting, using the one or more processors, a range to an object based on radar signal;
• and
• adjusting, using the one or more processors, the range based on a path loss associated with the removable case.

An electronic device comprising:

• an antenna configured to transmit radio-frequency signals;
• a voltage standing wave ratio (VSWR) sensor communicably coupled to the antenna, the VSWR sensor being configured to generate VSWR values from the radio-frequency signals transmitted by the antenna;
• and
• one or more processors configured to
• detect a range to an object based on the radio-frequency signals transmitted by the antenna, and
• adjust the detected range to compensate for a removable case detected, by the one or more processors, based on the VSWR values.
