Microwave Sensors
SA Photonics has developed an entirely passive, optically connected, high power microwave (HPM) situational awareness threat sensor (SATS) to detect and characterize HPM attacks. The sensor, which is entirely passive, translates incoming HPM energy into modulated optical signals and sends them via fiber-optic cable to a processing unit where the signals are characterized.
By remoting the passive sensor from the active electronics via a non-conductive optical cable, extremely high power densities can be accommodated without damaging the active electronics. In addition, the sensor has a dynamic range in excess of 40 dB, allowing a wide range of threat power level detection. Bandwidths up to 50 GHz can be supported.
