NTHAB Dual-Frequency GNSS Anti-Jamming Processor Overview
The NTHAB Satellite Navigation Dual-Frequency Anti-Jamming Processor is an 8-channel anti-jamming processor that supports two RF signal processing modes: single-frequency with eight elements or dual-frequency with four elements [source: 4]. It possesses suppression capability for suppressive jamming in various forms, including broadband, narrowband, frequency-sweeping, pulse, and combined jamming [source: 4]. Its processing frequency points and bandwidth are dynamically configurable, supporting anti-jamming processing for frequency points such as GPS/BDS L1/L2/L5 and BDS B1/B2/B3 [source: 4]. Adopting a low-cost, miniaturized, and lightweight design, it is suitable for precise navigation needs in complex electromagnetic environments, delivering performance especially in the UAV field [source: 4].
NTHAB Dual-Frequency GNSS Anti-Jamming Processor Primary Capabilities
- Flexible Array Reconfiguration: Accommodates multi-mode RF processing setups deploying either an 8-element single-frequency layout or a 4-element dual-frequency topology based on threat profiles [source: 4].
- Multi-Constellation Band Compatibility: Extends full coordinate protection matrices across global multi-system bands, maintaining operational link compatibility with BDS-B1, BDS-B3, GPS-L1, GPS-L2, GLONASS-L1, and Galileo-E1 channels [source: 4].
- Dynamic Bandwidth Configuration: Executes real-time hardware adaptations through dynamically configurable processing frequency points and flexible operational bandwidth limits to isolate complex ambient interference [source: 4].
- Deep Spatial Nulling Thresholds: Provides hardware attenuation values reaching single interference ≥110dB, three simultaneous sources ≥95dB, and up to seven concurrent interferences at ≥80dB [source: 4].
- Multi-Directional Disruption Defense: Employs parallel digital filters engineered to isolate and neutralize suppressive wavefronts arriving from 3 to 7 independent directional vectors simultaneously [source: 4].
- Broadband Noise Mitigation: Identifies and dampens continuous or transient ambient RF vulnerabilities such as broadband emissions, narrowband carrier lock, pulse transients, and frequency-sweeping signatures [source: 4].
