Abstract
Methods, apparatus, systems and articles of manufacture are disclosed to improve Doppler velocity estimation. An example apparatus is disclosed including a transmitter to transmit a first sweep signal at a first position in a first block of time during a transmit time sequence pattern, and transmit a second sweep signal at a second position in a second block of time during the transmit time sequence pattern, the second position different than the first position. The example apparatus also includes a velocity analyzer to determine a velocity and a direction of arrival of a target object identified during the transmit time sequence pattern.
Claims26
An apparatus comprising:
- a transmitter to:
- transmit a first sweep signal at a first position in a first block of time during a transmit time sequence pattern;
- transmit a second sweep signal at a second position in a second block of time during the transmit time sequence pattern, the second position different than the first position;
- and
- a velocity analyzer to determine a velocity and a direction of arrival of a target object identified during the transmit time sequence pattern.
A non-transitory computer readable medium comprising instructions that, when executed, cause a machine to at least:
- transmit a first sweep signal from a first transmit antenna at a first position in a first block of time during a transmit time sequence pattern;
- transmit a second sweep signal from the first transmit antenna at a second position in a second block of time during the transmit time sequence pattern, the second position different than the first position;
- and
- determine a velocity and a direction of arrival of a target object identified during the transmit time sequence pattern.
A method comprising:
- causing, by executing an instruction with a processor, transmission of a first sweep signal from a first transmit antenna at a first position in a first block of time during a transmit time sequence pattern;
- causing, by executing an instruction with the processor, transmission of a second sweep signal from the first transmit antenna at a second position in a second block of time during the transmit time sequence pattern, the second position different than the first position;
- and
- determining, by executing an instruction with the processor, a velocity and a direction of arrival of a target object identified during the transmit time sequence pattern.
An apparatus comprising:
- means for transmitting to:
- transmit a first sweep signal from a first transmit antenna at a first position in a first block of time during a transmit time sequence pattern;
- transmit a second sweep signal from the first transmit antenna at a second position in a second block of time during the transmit time sequence pattern, the second position different than the first position;
- and
- means for analyzing velocity to determine a velocity and a direction of arrival of a target object identified during the transmit time sequence pattern.
