1. A method for utilizing radar from wireless earpieces, comprising: (9) (3)

activating one or more radar sensors of the wireless earpieces;

performing radar measurements of a user using the one or more radar sensors of the wireless earpieces; and

analyzing the radar measurements to determine pulsatile measurements associated with the user, the analyzing performed using a processor of the wireless earpieces.

2. The method of claim 1, wherein the one or more radar sensors are internally focused on an ear of the user. (0)

3. The method of claim 1, wherein the one or more radar sensors are encompassed by a frame of the wireless earpieces. (0)

4. The method of claim 1, wherein the one or more radar sensors include a first set of sensors that are internally focused toward the user and a second set of sensors that are externally focused away from the user. (0)

5. The method of claim 1, further comprising: (1) (1)

7. The method of claim 1, further comprising: (0) (1)

8. The method of claim 1, further comprising: (0) (1)

9. The method of claim 1, further comprising: (0) (1)

10. The method of claim 1, wherein the pulsatile measurements include one or more of heart rate, heart rate variability, blood flow velocity, blood pressure, and respiration rate. (0)

11. The method of claim 1, further comprising: (0) (1)

12. A wireless earpiece, comprising: (4) (5)

an earpiece housing for fitting in an ear of a user;

a processor controlling functionality of the wireless earpiece;

a plurality of sensors perform sensor measurements of the user, wherein the plurality of sensors include one or more radar sensors;

a transceiver capable of communicating with at least a wireless device;

wherein the processor activates the one or more radar sensors to perform radar measurements, and analyzes the radar measurements to determine pulsatile measurements associated with the user.

13. The wireless earpiece of claim 12, wherein the one or more radar sensors include internally and externally facing radar sensors. (0)

14. The wireless earpiece of claim 12, wherein the processor compares a baseline radar signature of the user with a radar signature read by the one or more radar sensors to identify the user. (0)

15. The wireless earpiece of claim 12, wherein the pulsatile measurements include one or more of heart rate, heart rate variability, blood flow velocity, blood pressure, and respiration rate. (0)

16. The wireless earpiece of claim 12, wherein the processor isolates a Doppler frequency of a blood flow velocity from a composite signal represented by the radar measurements. (0)

17. The wireless earpiece of 12, wherein the processor determines the motion of the wireless earpiece, and positioning of the wireless earpiece relative to a head of the user. (0)

18. A wireless earpiece, comprising: (0) (5)

an earpiece housing adapted to fit into an ear of a user;

a processor for executing a set of instructions, the processor disposed within the earpiece housing;

at least one radar sensor operatively connected to the processor;

a memory operatively connected to the processor for storing the set of instructions, wherein the instructions are executed to:

activate one or more of the at least one radar sensors of the wireless earpieces, perform radar measurements of the user, and analyze the radar measurements to determine pulsatile measurements associated with the user.
