METHOD AND APPARATUS WITH RADAR SIGNAL PROCESSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18496145 titled 'METHOD AND APPARATUS WITH RADAR SIGNAL PROCESSING
Simplified Explanation
The radar signal processing method described in the abstract involves extracting chirp sequence signals of different carrier frequencies from a radar signal received through an array antenna in a radar sensor. These signals are then used to generate a range-Doppler map, detect target cells, determine Doppler velocities, and estimate ambiguous Doppler velocities to ultimately determine the Doppler velocity of a target.
- Extract chirp sequence signals of different carrier frequencies from radar signal

Original Abstract Submitted
A radar signal processing method includes: extracting a first chirp sequence signal of a first carrier frequency and a second chirp sequence signal of a second carrier frequency from a radar signal received through an array antenna in a radar sensor; generating a first range-Doppler map by performing frequency conversion on the first chirp sequence signal; detecting a first target cell corresponding to a first target in the first range-Doppler map; determining a first ambiguous Doppler velocity of the first target based on first frequency information of the first target cell; determining a first range of an unambiguously measurable Doppler velocity through the first chirp sequence signal; estimating second ambiguous Doppler velocities based on the first ambiguous Doppler velocity and the first range; and determining a Doppler velocity of the first target by performing partial frequency conversion on the second chirp sequence signal based on the second ambiguous Doppler velocities.
