Abstract

A method of forming a virtual three-dimensional radar display on a radar page comprising the steps of (i) establishing a split window display showing a 2-dimensional view of altitude representation of own ship and target'"'"'s information; and (ii) combining range and azimuth information onto the radar page, thereby the radar page provides the pilot of an aircraft with a three-dimensional perspective of the own ship and targets'"'"' profile. The three-dimensional perspective of the own ship and targets information greatly enhances the situation awareness of the pilot.

Claims

1. A method of forming a virtual three-dimensional radar display on a radar page, said radar page including target information of at least one target detected by a radar system, said method comprising the steps of:

establishing a split window display showing a 2-dimensional view of altitude representation of own aircraft and target'"'"'s information; and

combining range and azimuth information onto the radar page, thereby the radar page providing the pilot of an aircraft with a three-dimensional perspective of the craft and targets'"'"' profile.

2. The method of claim 1, wherein the split window display consists of a 2-dimensional own aircraft symbol changing dynamically to provide a three-dimensional perception.

3. The method of claim 1, wherein the split window display further consists of targets'"'"' symbol represented in altitude against azimuth.

4. The method of claim 3, wherein the target information in the altitude against azimuth display corresponds to the targets information in the B scope display of the radar display.

5. The method of claim 1, wherein the combination of the altitude against azimuth display and the B scope display gives a three dimensional perspective.

6. The method of claim 1, wherein the flight information includes a simulated altitude direction indicator incorporated to the radar page.

7. The method of claim 4, wherein the simulated altitude direction indicator includes a horizon of blue and brown background underlying the radar B scope and a heading scale running underneath the radar azimuth scale.

8. An apparatus for forming a virtual three-dimensional radar display on a radar page comprising the steps of:

means for establishing a split window display showing a 2-dimensional view of altitude representation of own aircraft and target'"'"'s information; and

means for combining range and azimuth information onto the radar page, thereby the radar page providing a pilot of an aircraft with a three-dimensional perspective of the own aircraft and targets'"'"' profile.

9. The apparatus of claim 8, wherein the split window display consists of a 2-dimensional own aircraft symbol changing dynamically to provide a three-dimensional perception.

10. The apparatus of claim 8, wherein the split window display further consists of targets'"'"' symbol represented in altitude against azimuth.

11. The apparatus of claim 10, wherein the target information in the altitude against azimuth display corresponds to the targets information in the B scope display of the radar display.

12. The apparatus of claim 8, wherein the combination of the altitude against azimuth display and the B scope display gives a three dimensional perspective.

13. The apparatus of claim 8, wherein the flight information includes a simulated altitude direction indicator incorporated to the radar page.

14. The apparatus of claim 11, wherein the simulated altitude direction indicator includes a horizon of blue and brown background underlying the radar B scope and a heading scale running underneath the radar azimuth scale.

15. A radar system for detecting and displaying at least one target comprising:

a radar page comprising a virtual three-dimensional radar display, where in said virtual three-dimensional radar display comprises;

a split window display showing a 2-dimensional view of altitude representation of own aircraft and target'"'"'s information; and

a secondary display within said split window display presenting a combined range and azimuth information onto the radar page,

said the radar page providing a pilot of an aircraft with a three-dimensional perspective of the own aircraft and targets'"'"' profile.

16. The radar system of claim 15, wherein the split window display consists of a 2-dimensional own aircraft symbol changing dynamically to a three-dimensional perception.

17. The radar system of claim 15, wherein the split window display further consists of targets'"'"' symbol represented in altitude against azimuth.

18. The radar system of claim 17, wherein the target information in the altitude against azimuth display corresponds to the targets information in the B scope display of the radar display.

19. The radar system of claim 15, wherein the combination of the altitude against azimuth display and the B scope display gives a three dimensional perspective.

20. The radar system of claim 15, wherein the flight information includes a simulated altitude direction indicator incorporated to the radar page.

21. The radar system of claim 18, wherein the simulated altitude direction indicator includes a horizon of blue and brown background underlying the radar B scope and a heading scale running underneath the radar azimuth scale.
