1. A method of wireless communications at a vehicle user equipment (UE), comprising:
receiving, at a first radar component of the vehicle UE, a first radar waveform in a field of view of the first radar component, wherein the first radar waveform indicates a set of motion parameters for a target vehicle UE;
determining a trajectory of the target vehicle UE based at least in part on the set of motion parameters for the target vehicle UE, one or more previous radar waveforms received at the first radar component, and the target vehicle UE exiting the field of view of the first radar component, wherein the trajectory indicates the target vehicle UE is to exit the field of view of the first radar component of the vehicle UE and, after being out of range of the first radar component, is to enter a field of view of a second radar component of the vehicle UE different than the first radar component at a time of entry and at a set of coordinates, and wherein the trajectory indicates that the target vehicle UE is to enter the second radar component with a velocity of entry;
storing information associated with the set of motion parameters for the target vehicle UE and the trajectory of the target vehicle UE on a database associated with the vehicle UE;
receiving, at the second radar component of the vehicle UE, a second radar waveform in the field of view of the second radar component;
accessing, by the second radar component, the stored information associated with the set of motion parameters for the target vehicle UE, the stored trajectory of the target vehicle UE, or both on the database based at least in part on receiving the second radar waveform in the field of view of the second radar component; and
associating the second radar waveform with the target vehicle UE based at least in part on accessing the stored information, the stored trajectory, or both of the target vehicle UE.
