Claim 0:
1. A method comprising:
at an electronic device that includes a plurality of radar-based transmitters and one or more radar-based receivers;
transmitting, from the plurality of radar-based transmitters, radio waves into an area in a vicinity of the electronic device, wherein the transmitting is performed according to a transmission operating mode selected from a plurality of transmission operating modes including:
a first mode in which each radar-based transmitter transmits in sequence such that the one or more radar-based receivers are activated after transmitting from one of the plurality of radar-based transmitters and before transmitting from another one of the plurality of radar-based transmitters; and
a second mode in which each of the radar-based transmitters transmits simultaneously;

receiving, at the one or more radar-based receivers, the radio waves reflected off one or more objects in the vicinity of the electronic device; and
processing the radio waves as reflected off the one or more objects using a radar imaging module;

wherein the electronic device includes a display, and wherein the transmitting includes:
transmitting, from a first set of the plurality of radar-based transmitters, first radio waves, wherein the first set of the plurality of radar-based transmitters face inward toward a center of the display and transmit a majority of the first radio waves in a direction parallel to the display; and
transmitting, from a second set of the plurality of radar-based transmitters, second radio waves, wherein the second set of the plurality of radar-based transmitters face outward from the display and transmit a majority of the second radio waves in a direction that is perpendicular to the display.
