MOVING-ENTITY DETECTION
First Claim
1. A method for detecting entities based on movement, the method comprising:
- transmitting a stepped-frequency radar signal from a first side of a wall to a second side of the wall;
detecting reflections of the transmitted signal with an antenna while the antenna is in motion;
determining one or more characteristics of motion of a system which includes the antenna during the detection of reflections of the transmitted signal;
generating data including information associated with frequency and phase shifts between the transmitted signal and the reflections of the transmitted signal detected with the antenna while the antenna is in motion; and
analyzing the generated data to determine information associated with a moving object located beyond the second side of the wall, the analyzing including using the determined one or more characteristics of the motion of the system to compensate for the effect of the motion of the system on the phase shifts between the transmitted signal and the reflections of the transmitted signal.

Abstract
A system and method for detecting entities based on movement can involve transmission circuitry configured to enable transmission of a stepped-frequency radar signal, an antenna, and receiving circuitry configured to generate data including information associated with frequency and phase shifts between the transmitted signal and the reflections of the transmitted signal. The system also can involve a processor configured to analyze the generated data to determine information associated with a moving object located at a side of a wall different than a side of the wall of which the system is located. The analyzing can involve compensating for the effect of motion of the system on the phase shifts between the transmitted signal and the reflections of the transmitted signal.
