Object range and velocity detection from varying radar pulse repetition times

A method, comprising

• transmitting, with a radar system, a frame including a series of electromagnetic pulses having a varying pulse repetition time between each electromagnetic pulse in the series, and each electromagnetic pulse in the series having a center frequency that varies from the center frequency of the other electromagnetic pulses in the series by a frequency step, the pulse repetition time based on the frequency step of the respective electromagnetic pulse;
• receiving, with the radar system, a corresponding series of reflected pulses that reflect from an object in response to the frame;
• determining, by the radar system, range and velocity information of the object based on the corresponding series of reflected pulses, the range information based on a single reflected pulse of the corresponding series of reflected pulses and on combined reflected pulses of the series of reflected pulses;
• and
• varying, with the radar system, the pulse repetition time based on a count of a number of repetitions, an initial center frequency, and an initial pulse repetition time.

A system comprising:

• a processor configured to:
• control a transmitter to transmit a radar frame including a series of electromagnetic pulses having a varying pulse repetition time between each electromagnetic pulse in the series, and each electromagnetic pulse in the series having a center frequency that varies from the center frequency of the other electromagnetic pulses in the series by a frequency step, the pulse repetition time based on the frequency step of the respective electromagnetic pulse;
• control a receiver to receive a corresponding series of reflected pulses that reflect from an object in response to the radar frame;
• determine range and velocity information of the object based on the corresponding series of reflected pulses, the range information based on a single reflected pulse of the corresponding series of reflected pulses and on combined reflected pulses of the series of reflected pulses;
• and
• vary the pulse repetition time based on a number of repetitions, an initial center frequency, and an initial pulse repetition time.
