Remote Sensing
Phased Array and Remote Sensing Signal Acquisition System
Provides synchronized acquisition and real-time transmission for multi-channel IF signals, supporting backend signal processing validation.
Project Background
Users need to perform synchronized multi-channel signal acquisition during the intermediate frequency stage for validating array signal processing algorithms. The existing acquisition equipment has limited channel count, and synchronization accuracy between channels fails to meet requirements, resulting in unstable algorithm validation outcomes.
Technical Solution
- Build an acquisition array using multiple quad-channel synchronous acquisition cards, achieving channel-level synchronization via shared clock and trigger signals.
- Add decimation filtering to the acquisition chain to balance data rate and transmission bandwidth.
- Comes with a collection and control software that supports configurable collection duration and storage policies on demand.
Products Used
- High-Speed Data Acquisition Board XH-ADC4000
- Signal Processing Carrier Board XH-FPGA900
Implementation effect
The acquisition channel scale and synchronization accuracy meet the requirements for array algorithm validation. Standardized acquisition workflows significantly reduce preparation time for repeated experiments.
