Multi-Channel Direction-Finding Systems Using Radio Waves TRIZ Cases
- Radar Signal Processor Power Estimation via Adjacent Azimuth Matrix
An approximating expression limits the inverse matrix to adjacent azimuth elements, reducing computational volume for real-time collision avoidance.
- Wideband RF Direction Finding via FFT Phase Analysis
A wideband direction finding system processes signals using Fast Fourier Transform to resolve phase data for azimuth and elevation estimates.
- GNSS Signal Processing Attenuating Jamming via Covariance Analysis
A GNSS receiver method detects jamming directions using antenna covariance matrices to attenuate interference signals.
- Joint Angle-Frequency Determination via SOCP
Second Order Cone Program analysis jointly resolves signal angles and frequencies, reducing processing power consumption compared to iterative sparse methods.
