Apparatus and method for remote analysis of a target device
First Claim
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.

Abstract
An apparatus and method that intentionally illuminate a number of target devices with RF energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.) are provided. The target devices, which may comprise a computer system or other electronic circuits, by their fundamental nature as mixed analog and digital devices, act as non-linear mixers and are forced to emit information about the target device behavior, state, and physical characteristics. The apparatus that implements the method receives the forced emissions signals, extracts useful data from noise, and analyzes the data to determine target device characteristics. The target devices may be powered or unpowered. The apparatus and method provided may avoid impacting target device operation.
