Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 7:
8. A radar method, comprising:
generating, by a processor of a radar system, a chirp frame comprising a plurality of linear frequency modulated chirps;
modulating, by the processor, a first portion of a chirp of the plurality of linear frequency modulated chirps according to a first phase;
modulating, by the processor, a second portion of the chirp in the chirp frame according to a second phase;
combining, by the processor, the first and second portions of the chirp to produce a phase-modified chirp; and
instructing, by the processor, first and second subsets of transmitters, of a set of transmitters of the radar system, to transmit the phase-modified chirp using time division multiple access (TDMA) and by directing radio frequency energy according to a target angle and a target gain, the first and second subsets of transmitters having a transmitter in common;
demodulating, by the processor, a received signal to obtain the chirp based on a difference in phase values of the first phase and the second phase; and
performing a Doppler fast Fourier transform (FFT) on the received signal.
