System and Method for Detecting Dangerous Objects and Substances
First Claim
1. A method, comprising:
- generating a microwave signal that is reflected by a target to render one or more reflected signals;
receiving the one or more reflected signals at an antenna array;
converting the one or more reflected signals into digital reflected signals;
converting the microwave signal into a digital signal;
processing the digital reflected signals and the digital signal to determine the three dimensional position of the target;
processing the digital reflected signals and the digital signal to identify the target;
processing the digital reflected signals and the digital signal to determine a state of the target; and
determining whether the target is a dangerous object.

Abstract
A system and method for detecting dangerous objects and substances are disclosed. According to one embodiment, a method comprises generating a microwave signal that is reflected by a target to render one or more reflected signals. The one or more reflected signals are received at an antenna array. The one or more reflected signals are converted into digital reflected signals. The microwave signal is converted into a digital signal. The digital reflected signals and the digital signal are processed to determine the three dimensional position of the target. The digital reflected signals and the digital signal are processed to identify the target. The digital reflected signals and the digital signal are processed to determine a state of the target; and determine whether the target is a dangerous object.
