Abstract
Certain aspects provide a method for radar detection by an apparatus. The method generally includes transmitting a radar waveform in sets of transmission time intervals (TTIs), using a common set of radar transmission parameters in each set of TTIs, to perform detection of a target object, varying at least one of the common set of radar transmission parameters between sets of TTIs, and identifying interfering signals based on observed changes in monitored parameters of received signals across sets of TTIs due to the varying.

A method for radar detection by an apparatus, comprising:
- transmitting a radar waveform in sets of transmission time intervals (TTIs), using a common set of radar transmission parameters in each set of TTIs, to perform detection of a target object;
- varying at least one radar transmission parameter of the common set of radar transmission parameters between sets of TTIs;
- and
- identifying interfering signals based on observed changes in monitored parameters of received signals across sets of TTIs, wherein the observed changes are the result of the varying of the at least one radar transmission parameter.
A radar detection apparatus comprising:
- a memory;
- and
- a processor communicatively coupled to the memory, wherein the processor is configured to:
- transmit a radar waveform in sets of transmission time intervals (TTIs), using a common set of radar transmission parameters in each set of TTIs, to perform detection of a target object;
- vary at least one radar transmission parameter of the common set of radar transmission parameters between sets of TTIs;
- and
- identify interfering signals based on observed changes in monitored parameters of received signals across sets of TTIs, wherein the observed changes are the result of the varying of the at least one radar transmission parameter.
