Abstract

Aspects of the present disclosure relate to visual presentation techniques for micro-Doppler signatures.

Claims

1. A method, comprising:

a. Receiving an mD signature indicative of a human presence at a location in an obscured environment;

b. Establishing a virtual location marker in a position that is visually available to a person wearing a HWC, wherein the virtual marker provides an indication of the location in the obscured environment; and

c. Generating an avatar as a representation of the human presence and presenting the avatar in a field of view of the HWC, wherein the presentation of the avatar is positioned in the field of view by visually associating the avatar with the location marker such that the avatar appears to remain at the location marker location, as perceived by a person wearing the HWC, independent of the HWC'"'"'s viewing angle.

2. The method of claim 1, further comprising:

establishing an identity of the human presence and presenting an indication of the identity in the field of view.

3. The method of claim 2, wherein the indication is a color of the avatar.

4. The method of claim 2, wherein the identity is of an enemy combatant.

5. The method of claim 1, wherein the human presence at the location in the obscured environment moves within the obscured environment;

and the virtual location marker moves to continue to provide the indication of the location in the obscured environment.

6. The method of claim 1, wherein an mD radar that established the mD signature is remotely located from the person wearing the HWC.

7. The method of claim 1, wherein an mD radar that established the mD signature is proximate to the person wearing the HWC.

8. A method, comprising:

a. Viewing a human presence through a field of view of a head worn computer in an environment until the human presence enters an obscured location in the environment;

b. Receiving an mD signature indicative of the human presence at the obscured location;

c. Establishing a virtual location marker at a position that is visually available to a person wearing the head worn computer, wherein the virtual marker provides an indication of the obscured location;

d. Generating an avatar as a representation of the human presence and presenting the avatar in a field of view of the head worn computer, wherein the presentation of avatar is positioned in the field of view by visually associating the avatar with the location marker such that the avatar appears to remain at the location marker location, as perceived by a person wearing the HWC, independent of the head worn computer'"'"'s viewing angle.
