Abstract
A radar sensing system for a vehicle includes transmit and receive pipelines. The transmit pipeline includes transmitters able to transmit radio signals. The receive pipeline includes receivers able to receive signals. The received signals are transmitted signals that are reflected from an object. The transmit pipeline phase modulates the signals before transmission, as defined by a first binary sequence. The receive pipeline comprises an analog to digital converter (ADC) for sampling the received signals. The transmit pipeline includes a pseudorandom binary sequence (PRBS) generator for outputting a second binary sequence of bits with an equal probability of 1 and 0. The first binary sequence is defined by least significant bit (LSB) outputs from the ADC and the second binary sequence of bits. The first binary sequence comprises a truly random unbiased sequence of bits with an equal probability of 1 and 0.
