SPC's Radar Physics Group has developed a PC-based multi-channel, high-speed Analog/Digital Data Recorder (ADDR).
The ADDR combines commercial-off-the-shelf (COTS) PCI I/O and data streaming cards with custom software to provide
ultra-fast throughput to disk on an easy-to-use system. In addition to offering a simple user interface, ADDR
control software provides tools for off-line data extraction. The entire system is contained in a ruggedized,
rack-mountable chassis.
By integrating ADDR with the MkVe instrumentation radar, SPC has
greatly augmented the overall system capability. ADDR adds the capability of recording continuous range data,
allowing the MkV to be used in applications for which data must be collected simultaneously over multiple ranges.
Using the ADDR to sample radar video data, continuous range data can be collected. SPC's
Pulse Doppler Processing software offers extensive processing capability for
this type of data.
Operation
As data is acquired, it is transferred directly to a COTS PCI disk-streaming card through the computer's PCI bus or
a standard external interface. This direct data transfer allows dataflow to bypass the operating system, therefore
eliminating any delays caused by task management or software latency. Data rates are limited only by the interface
bandwidth. If higher aggregate data rates are required, input channels may be distributed across multiple cards
with the user interface provided by a single CPU. Furthermore, FIFO buffers in the A/D cards allow triggered,
non-continuous collections at burst rates that exceed the continuous throughput of the bus.
Because ADDR uses standard SATA or IDE hard drives, it benefits from advances in hard drive technology, leading to
increased storage capacity at minimal additional cost.
