Abstract
A method of radar signal processing includes providing an analog front end (AFE) including an amplifier coupled between an antenna and an ADC in a receive path, where an ADC output is coupled to an input of an elastic ADC buffer (elastic buffer) including a divided memory with for writing samples from the ADC (samples) while reading earlier written samples to a first signal processor by a high speed interface. A transmit path includes at least one power amplifier provided by the AFE coupled to drive an antenna. A Greatest Common Divisor (GCD) is determined across all chirps in a radar frame programmed to be used. For each frame a sample size for the elastic buffer is dynamically controlled constant to be equal to the GCD for reading samples from one memory block and writing samples to another memory block throughout all chirps in the frame.
