Abstract
Methods, systems, and devices for radar signaling s are described. In some systems, devices may select radar parameters (e.g., frequency modulated continuous wave waveform parameters) to support coexistence for multiple radar sources in the system. To reduce mutual interference between radar waveforms in a system, a user equipment may detect interference from at least one interference source (e.g., another device transmitting a radar waveform) and may select waveform parameters for transmission of a radar waveform based on the detected interference. For example, the user equipment may determine slopes, frequency offsets, codewords, or a combination thereof used by nearby devices in the system (e.g., per chirp or for a waveform) and may select waveform parameters that result in low mutual interference with the determined slopes, frequency offsets, codewords, or combination thereof. The user equipment may transmit the radar waveform according to the selected waveform parameters.
