Oceanographic Radar/Sonar Controller
New product provides a complete Radar/Sonar controller in a stack.
Radar/Sonar clock generation module "RADCELF" plugs on to an ACQ1001 module stack to make a complete system, enabling a new generation of frequency-modulated continuous wave (FMCW) radars and sonars with smaller size, lower cost, lower power dmeand and uncompromised performance.
eg pictured product comprises:
- RADCELF Triple DDS controller for all local clock generation, control to the micro-hertz
- ACQ435-32 32 channels simultaneous 24 bit digitizer
- ACQ1001 intelligent controller with choice of Ethernet or USB output.
The RADCELF triple DDS unit is a COTS module for complete signal generation, featuring
- Support for local oven controlled oscillator with temperature stabilization.
- 3 x AD9854 DDS units, 48 bit tuning word resolution, I+Q outputs and many operating modes.
- Output filtered by user-selectable SMD filters (Mini Circuits recommended).
- Flexible clock routing using soft switchable clock dividers.
- Completely software programmable, with critical lines controlled by FPGA to facilitate complex timing scenarios
- Additional slow IO and USB2 port for expansion
eg support for GPS ONEPPS time sync.
| Typical scenarios | |
|---|---|
| 8 antenna, 16 complex channel HF radar | ACQ1001+ACQ435-16+RADCELF (shown) |
| 16 antenna, 32 complex channel HF radar | ACQ1001+ACQ435-32+RADCELF |
| Expand to 96 channel | chain additional ACQ1002+2xACQ435ELF-32 unit |
| High bandwidth for active sonar, 500kHz, 32 channels x 1000kSPS | substitute ACQ424ELF-32 |
| High bandwidth for microwave radar, 1MHz, 16 channels x 2MSPS | substitute ACQ425ELF-16-2000 |
| High bandwidth for microwave radar, 25MHz, 8 channels x 50MSPS | substitute ACQ480ELF |
