A man-portable phased array ISR system includes a multilayer panel. A first panel layer includes a subarray layer having a plurality of sensors for detecting and receiving radiofrequency information. A second panel layer includes a digital data storage system to digitize, record and store the radiofrequency information. A third panel layer includes a command and communication link. A fourth panel layer includes a nanoparticle ultra-capacitor energy storage system adapted to provide power to the subarray, to the digital data storage system and to the command and communication link. The plurality of sensors may be receive-only sensors for radio-frequency data collection. The first panel layer may include integral beamforming systems having a predetermined frequency range for transmit an receive radar signal formation and data collection.
