Ext- SBSP solves radar




SBPS helps space radar – survivability and efficiency


Dinerman 7 (Taylor Dinerman, Consultant for DOD, Senior Editor at Hudson, “Solar Power Satellites and Space Radar,” 7/16/07.
In order to achieve the power levels needed for an effective GMTI system using current technology, very large solar arrays would be needed. Even if these were to use the new Boeing solar cells that, according to the company, are more than 30% efficient, the arrays would still be much bigger than anything on any operational satellite. Such large arrays would make the SR spacecraft easy targets for enemy antisatellite weapons and would also produce so much drag while in low Earth orbit (LEO) that their lifespan would be shorter—perhaps much shorter—than current-generation reconnaissance satellites. Why, then, does such a system need to rely 100% on its own power? If solar power satellites (SPS) were available in geosynchronous orbit and could beam electricity to the SR satellites in LEO, this might allow the radar satellites to have as much power as their power control systems and heat radiators could handle. Power could be transmitted by a tightly focused laser or microwave beam to one or two receptors, integrated into the spacecraft’s bus. If the radar antenna were integrated into the skin of the satellite the way it is on a B-2 bomber, such satellite would be difficult to detect and track. Using power from an SPS, such a satellite would be able to liberally use its ion engines to change its orbit. These engines would never be powerful enough to make the kind of quick responsive maneuvers that some space operations commanders would like to see in future LEO-based spacecraft, but they would be a step in the right direction.

SBPS increases radar coverage – better power generation


Ramos 2k (Kim, USAF Major and professor at the Air Command and Staff College Air University, “Solar Power Constellations Implications for the US Air Force.” April 2000. )
One of the reasons space-based radar has a limited viewing area is lack of enough power generating capability. Although the National Security Strategy does not currently call for force application from space, one of the technological issues is generating enough power to enable force application technologies. A solar power satellite could supply the power required for these technologies. Coupling space-based radar with a solar power satellite enables the radar to increase its coverage. Finally, the commercial communications satellite industry is under study as a possible power-generating source. Should this occur, a deployed unit could receive its communications and power from one microwave beamed source.

SBSP makes space-based radar realistic


Ramos 2k (Kim, USAF Major and professor at the Air Command and Staff College Air University, “Solar Power Constellations Implications for the US Air Force.” April 2000. )
A space-based radar concept is currently in work at an Air Force Research Laboratory. It requires large amounts of electrical power and the engineers have found no optimum solution to the problem. 31 The space-based radar in use today is limited in resolution and coverage by on- orbit power. 32 As with the space-based laser and RF jamming device, a space-based radar receiving power from a solar power satellite eliminates this problem.


We solve bistatic radar – counters ARM missiles and radar jammers


Naval Research Laboratory 9 (a US military scientific research institute, “Space-based Solar Power: Possible Defense Applications and Opportunities for NRL Contributions,” 10/23/09. )

Bistatic radar systems are generally well-suited to several specific applications where they outperform conventional monostatic radars, especially in real-world tactical scenarios. Notably, bistatic radars are of particular value in countering anti-radiation missile (ARM) threats, retro-directive radar jammers, and stealth radar technologies. They are inherently capable of implementing some processes, notably cluttertuning, that are impossible for monostatic radars [2]. Any SBSP satellite delivering RF energy to the surface can be used in a “hitchhiker” configuration, where the same RF downlink used to provide power to ground users can also be used as a coherent source of that RF energy for bistatic radar implementations. SBSP satellites used as RF sources for bistatic radar applications possess advantages over and above those afforded by more traditional satellites (e.g., GEO communication satellites, and GPS). Initially, SBSP bistatic systems will be able to operate at much higher effective isotropic radiated power (EIRP) than other spaceborne sources, providing orders of magnitude higher illumination of the surface, resulting in much higher signal to noise ratio (SNR), which allows detection of targets with much lower radar cross sections and minimizes an already lower threat from surface jammers. Instead of relying on coincidental illumination from more traditional spaceborne sources, SBSP RF illumination can be directed to specific tactical areas of interest, providing an “on-demand” capability as an adjunct to the SBSP’s primary power transmission mission.
