Radar sensor processing chain

A non-transitory computer readable medium having stored thereon instructions that, when executed by one or more processors, cause the one or more processors to:

• receive, with a first radio frequency (RF) receiver on a host platform, a radio signal in a first frequency range;
• convert the received radio signal in the first frequency range to a corresponding signal in a second frequency range;
• perform chirplet transform on the signal in the second frequency range;
• retrieve waveform parameters for at least a second RF receiver on the host platform;
• extract waveform information corresponding to at least the second RF receiver by utilizing results from the chirplet transform and the retrieved waveform parameters;
• generate a point cloud with the received radio signal and the extracted waveform information;
• store the point cloud in a memory device;
• coherently add collocated responses;
• interpolate extracted waveform information for multiple RF receivers that are non-equally distributed;
• and
• perform a maximum likelihood angle estimation to determine an angular location corresponding to the second RF receiver.

A method comprising:

• receiving a first radio signal with a first radio frequency (RF) receiver in a plurality of RF sensor suites on a host platform;
• converting the received first radio signal to a second frequency range with a heterodyne mixer;
• performing at least a chirplet transform on the converted signal in the second frequency range with at least one hardware processor;
• retrieving stored relative location information for a second RF receiver in the plurality of RF sensor suites with the at least one hardware processor;
• extracting radar waveform information corresponding to the second RF receiver in a processing stream corresponding to the first RF receiver by utilizing the retrieved information and results from the chirplet transform;
• generating a point cloud based on the converted signal in the second frequency range and the extracted radar waveform information with the at least one hardware processor;
• storing the point cloud in a memory system;
• coherently add collocated responses;
• interpolate extracted waveform information for multiple RF receivers that are non-equally distributed;
• and
• perform a maximum likelihood angle estimation to determine an angular location corresponding to the second RF receiver.
