A reflected energy detecting device includes a transmitter for transmitting an electromagnetic signal and a receiver for receiving a reflected electromagnetic signal. An antenna may be operatively connected with the transmitter and the receiver for radiating the electromagnetic signal and capturing the reflected electromagnetic signal and the antenna may be movable. A main controller may be provided for controlling operation of the transmitter and the receiver and the movement of the antenna and the reflected energy detecting device may further include at least one platform. The at least one platform may support a remote reflector that is dimensioned and configured to redirect the transmitted electromagnetic signal in a desired direction and a platform controller that is configured to communicate with the main controller and to maintain alignment between the remote reflector and the antenna.

The device of claim 1, further comprising a stabilizer and a vibration isolator disposed between the at least one elevated platform and the remote reflector.8. The device of claim 7, further comprising an actuator disposed between the at least one elevated platform and the remote reflector, the actuator being configured to provide rotational and translational relative movement between the at least one elevated platform and the remote reflector and wherein the platform controller is configured to control operation of the actuator.9. The device of claim 1, wherein the main controller and the platform controller communicate via at least one of wireless and wired communications.10. The device of claim 1, wherein the transmitted electromagnetic signal is transmitted in the radio frequency band.11. The device of claim 1, wherein the transmitted electromagnetic signal is transmitted in the light frequency band.12. The device of claim 1, wherein the at least one elevated platform is movable.13. The device of claim 1, wherein the at least one elevated platform is mobile.14. The device of claim 13, wherein the at least one elevated platform comprises at least one of a mobile tower, an airship, an aerostat, a piloted aircraft and an unpiloted aircraft.15. The device of claim 1, wherein the at least one elevated platform comprises a plurality of movable platforms.16. The device of claim 1, wherein the remote reflector comprises a reflective surface which is generally flat.17. The device of claim 1, wherein the remote reflector comprises a metallic substance.18. The device of claim 1, wherein the antenna is dimensioned and configured to focus the transmitted electromagnetic signal at the location of the at least one elevated platform.19. The device of claim 1, wherein the elevated platform further comprises position sensors being operatively connected with the platform controller.20. The device of claim 1, wherein the antenna comprises a directional antenna.21. A radar system for detecting a target, comprising:a ground-based transmitter transmitting an electromagnetic signal; a ground-based receiver; and an elevated platform comprising a reflector that redirects the transmitted electromagnetic signal in a desired direction, and redirects a reflected electromagnetic signal from a target to the ground-based receiver.
