Abstract
One preferred embodiment of the present invention provides a system and method for suppressing motion interference in a radar detection system. Briefly described, in architecture, one embodiment of the system, among others, can be implemented as follows. The system includes a signal generator that transmits microwave signals toward a target area. Also, the system includes a data control system to collect data from reflected microwave signals from the target area and to analyze the data in order to suppress unwanted motion interference generated by movement of the radar detection system. Other systems and methods are also provided.
Claims48
A radar detection system for suppressing motion interference, comprising:
- a signal generator to transmit microwave signals toward a target area, wherein the signal generator operates in one of a step frequency mode and a sweep frequency mode;
- and
- a data control system configured to collect data from reflected microwave signals received by the radar detection system from at least a moving object and an intervening structure between the radar detection system and the moving object in the target area and to analyze the data and suppress, in the signals, unwanted motion interference generated by movement of the radar detection system,
- wherein the data control system is further configured to identify the presence of the moving object in the target area from the signals received by the radar detection system from the target area.
A radar detection system for suppressing motion interference, comprising:
- means for transmitting microwave signals, wherein microwave signals are transmitted in one of a step frequency mode and a sweep frequency mode;
- means for collecting data from reflected microwave signals received by the radar detection system from at least a moving object and an intervening structure between the radar detection system and the moving object in the target area;
- means for suppressing, in the signals, unwanted motion interference generated by movement of the radar detection system;
- and
- means for identifying the presence of the moving object from the signals received by the radar detection system.
