Direction Finders TRIZ Cases
- Tethered Spinning Antenna for Virtual Phased Array Synthesis
Periodic antenna rotation synthesizes a virtual phased array to improve location accuracy while reducing noise interference from low-power signals.
- Direction Finding Using UWB Antenna Directivity Fields
UWB antenna forms two directivity fields to determine radio tag direction by equalizing field intensities, eliminating signal reflection errors.
- Dual Frequency AoA Estimation Resolving Antenna Spacing Ambiguities
Combining phase and time difference on arrival at multiple frequencies resolves antenna spacing ambiguities for accurate angle determination.
- Radar Device Speed Detection Using Stationary Object Correlation
A radar device uses correlation processing of returning signals to generate electric power profiles for precise relative speed detection.
- Radar Direction Determination Using MIMO-SIMO Velocity Ambiguity Correction
A radar system determines direction information by comparing angle data from multiple transmit and receive antennas.
