SIGNAL PROCESSING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18164398 titled 'SIGNAL PROCESSING METHOD AND APPARATUS
Simplified Explanation
The patent application describes a signal processing method and apparatus for radar systems. Here are the key points:
- The method involves obtaining echo signals from a radar system in two different modes: SIMO (Single Input Multiple Output) and MIMO (Multiple Input Multiple Output).
- In the SIMO mode, Nr1×M1 echo signals are obtained, which are echoes of M1 signals sent by the radar to a target.
- In the MIMO mode, Nt×Nr2×M2 echo signals are obtained, which are echoes of M2 signals sent by the radar to the target.
- The method includes two stages of signal processing: first processing on the SIMO signals and second processing on the MIMO signals.
- The first signal processing involves range FFT analysis, linear prediction, and Doppler FFT analysis on the Nr1×M1 signals.
- The second signal processing involves range FFT analysis and Doppler FFT analysis on the Nt×Nr2×M2 signals.
- The method also includes velocity matching ambiguity resolution processing based on the processed data from both the SIMO and MIMO modes.
Potential applications of this technology:
- Radar systems: The signal processing method can be applied to radar systems used in various fields such as aviation, defense, meteorology, and autonomous vehicles.
- Target tracking: The method can help in accurately tracking targets by resolving velocity ambiguities and improving the quality of echo signal processing.
Problems solved by this technology:
- Ambiguity resolution: The method addresses the issue of ambiguity in velocity matching by combining data from SIMO and MIMO modes, resulting in more accurate target tracking.
- Signal processing efficiency: The method optimizes the processing of echo signals by performing specific analysis techniques, leading to improved radar performance.
Benefits of this technology:
- Enhanced target tracking: By resolving velocity ambiguities, the method improves the accuracy of target tracking in radar systems.
- Improved radar performance: The optimized signal processing techniques used in the method enhance the efficiency and effectiveness of radar systems.
