Abstract
A system and method generate a signal for transmission by a radar system. A bit modulator outputs a bit of a binary code. A digital frequency controller outputs a range of frequencies. An order of the range of frequencies is based on the bit. A phase-locked loop generates a signal for transmission by the radar system. The signal includes a chirp comprising the range of frequencies in the order output by the digital frequency controller.
Claims10
A radar system, comprising:
- a bit modulator configured to output a bit of a binary code;
- a digital frequency controller configured to output a range of frequencies, wherein an order of the range of frequencies is based on the bit;
- and
- a phase-locked loop configured to generate a signal for transmission by the radar system, wherein the signal includes a chirp comprising the range of frequencies in the order output by the digital frequency controller.
