Abstract
Certain aspects provide a method for radar detection by an apparatus. The method including transmitting a radar waveform in transmission time intervals (TTIs) to perform detection of a target object. The method further includes varying the radar waveform across TTIs based on one or more radar transmission parameters.

A method for radar detection by an apparatus, comprising:
- transmitting a radar waveform in transmission time intervals (TTIs) to perform detection of a target object;
- selecting a subset of a plurality of radar transmission parameters based on a current condition of the apparatus by:
- selecting, as the subset, a first subset of the plurality of radar transmission parameters based on at least one of:
- a first threshold of interference or a first driving mode of the apparatus;
- and
- selecting, as the subset, a second subset of the plurality of radar transmission parameters based on at least one of:
- a second threshold of interference or a second driving mode of the apparatus, wherein the first subset is different than the second subset;
- and
- varying the radar waveform across multiple TTIs based on the selected subset of the plurality of radar transmission parameters, wherein the varying the radar waveform comprises varying values of at least one of the selected first subset of the plurality of radar transmission parameters or the selected second subset of the plurality of radar transmission parameters.
