Abstract
In one embodiment, a method includes configuring a radar transceiver to transmit a first number of radar pulses at a first pulse repetition frequency (PRF); and determining a first value corresponding to a first object based on a first radar data received in response to the first number of radar pulses. The first object is identified based on the first value being higher than a predetermined threshold value. The method also includes configuring the radar transceiver to transmit a second number of radar pulses at a second PRF that is higher than the first PRF; determining a second value of the first object based on a second radar data received in response to the second number of radar pulses; and associating the second value with information of the first object.

A method comprising, by a computing system:
- configuring a radar transceiver to transmit a first number of radar pulses at a first pulse repetition frequency (PRF);
- determining a first value corresponding to a first object based on a first radar data received in response to the first number of radar pulses, wherein the first object is identified based on the first value being higher than a predetermined threshold value;
- configuring the radar transceiver to transmit a second number of radar pulses at a second PRF that is higher than the first PRF;
- determining a second value of the first object based on a second radar data received in response to the second number of radar pulses;
- and
- associating the second value with information of the first object.
One or more computer-readable non-transitory storage media embodying software that is operable when executed to cause one or more processors to perform operations comprising:
- configuring a radar transceiver to transmit a first number of radar pulses at a first pulse repetition frequency (PRF);
- determining a first value corresponding to a first object based on a first radar data received in response to the first number of radar pulses, wherein the first object is identified based on the first value being higher than a predetermined threshold value;
- configuring the radar transceiver to transmit a second number of radar pulses at a second PRF that is higher than the first PRF;
- determining a second value of the first object based on a second radar data received in response to the second number of radar pulses;
- and
- associating the second value with information of the first object.
A computing system comprising:
- one or more processors;
- and
- one or more computer-readable non-transitory storage media coupled to one or more of the processors, the one or more computer-readable non-transitory storage media comprising instructions operable when executed by one or more of the processors to cause the computing system to perform operations comprising:
- configuring a radar transceiver to transmit a first number of radar pulses at a first pulse repetition frequency (PRF);
- determining a first value corresponding to a first object based on a first radar data received in response to the first number of radar pulses, wherein the first object is identified based on the first value being higher than a predetermined threshold value;
- configuring the radar transceiver to transmit a second number of radar pulses at a second PRF that is higher than the first PRF;
- determining a second value of the first object based on a second radar data received in response to the second number of radar pulses;
- and
- associating the second value with information of the first object.
