Multiple frequency fusion for enhanced point cloud formation

A computing system for processing radar data, the system comprising:

• at least one non-transitory computer readable medium comprising instructions stored thereon, wherein the instructions are effective to cause the computing system to:
• perform a downsampling function on a first set of preprocessed radar data when generating a first updated dataset, the first set of preprocessed radar data generated from a first set of received radar signals of a first frequency, wherein the first updated data set includes less data than the first set of preprocessed data based on the performance of the downsampling function;
• perform an upsampling function on a second set of preprocessed radar data when generating a second updated dataset, the second set of preprocessed radar data generated from a second set of received radar signals of a second frequency, wherein:
• the second updated dataset includes more data than the second set of preprocessed data based on the performance of the upsampling function, and
• the first frequency of the first set of radar signals is greater than the second frequency of the second set of radar signals;
• perform a range cross-correlation function on the first updated dataset;
• generate target signatures and ranges to associate with one or more objects based on the performance of the range cross-correlation function;
• perform a Doppler cross-correlation function on the second updated dataset;
• and
• generate velocity data to associate with the target signatures and the ranges associated with the one or more objects based on the performance of the Doppler cross-correlation function.
