Claim:
1. A radar sensing system for a vehicle, the radar sensing system comprising: a transmit pipeline comprising a plurality of transmitters configured for installation and use on a vehicle, and operable to transmit radio signals; a receive pipeline comprising a plurality of receivers configured for installation and use on the vehicle, and operable to receive radio signals, wherein the received radio signals are transmitted radio signals that are reflected from an object; wherein the transmit pipeline is further operable to phase modulate the radio signals before transmission, and wherein the phase modulation is defined by a first binary sequence; wherein the receive pipeline comprises at least one analog to digital converter (ADC) operable to sample the received radio signals; wherein the transmit pipeline further comprises a pseudorandom binary sequence (PRBS) generator operable to output a second binary sequence of bits with an equal probability of 1 and 0; and wherein the transmit pipeline is further operable to define the first binary sequence at least in part by (a) least significant bit (LSB) outputs from the at least one ADC and (b) the second binary sequence of bits output from the PRBS generator, and wherein the first binary sequence comprises a truly random unbiased sequence of bits with an equal statistical probability of 1 and 0.
