1. A software defined radio (SDR) apparatus configured to remotely analyze a target device, the apparatus comprising:

  • transmitter circuitry configured to illuminate the target device with electromagnetic energy at a carrier frequency that mixes with operational electromagnetic signals in the target device to produce forced non-linear emissions (FNLE) that radiate from the target device;

    receiver circuitry configured to receive the FNLE from the target device, the FNLE including sidebands around the carrier frequency; and

    processing circuitry to determine one or more operational electromagnetic signal characteristics or one or more physical characteristics of the target device based on the received FNLE.
