SPS Effects on Optical and Radio Astronomy

• Rectenna Scattering: If 2% of incident power is scattered, the rectenna forms a 120-MW transmitter at 2.45 GHz. • Harmonic Emission: • Thermal Noise: Thermal emission from SPS could interfere with many observations. • Test Systems: Initial, low-power tests of components of the SPS could seriously damage radio astronomy observations.
