Features Overview
ŠŠDual-channel, dual-trigger radar interface card Osiris is a high-performance,
dual-channel radar interface board
ŠŠPMC or half-length PCI form factor that accepts and processes analog and
ŠŠSupports two Analog inputs (four on Osiris-B), and up to digital radar signals and provides a PCI interface to
eight digital input bits with flexible video mixing options applications. Osiris comes from a long history of radar
interface products at Curtiss-Wright, with interfaces to
ŠŠGain and offset control as a function of range support many legacy and modern radar types. With an
ŠŠFlexible LUT-based digital filtering including low- and on-board FPGA and high-speed PCI interface, Osiris offers
high-pass high performance with two independent channels on a half-
length PCI or PMC mezzanine format.
ŠŠBIT generator with multiple test patterns
ŠŠDual-azimuth input (supports ACP/ARP, RADDS, serial Operation
and parallel formats)
Osiris receives all radar video, triggers and azimuth data
ŠŠFlexible input configuration options (single-ended/ from a front-panel connector. It can generate two streams

of radar video onto the PCI bus. Each of the two streams
ŠŠCorrelation in azimuth and range can process data from a combination of the analog and
digital inputs, using one of two sets of trigger and turning
ŠŠSampling rate up to 50 MHz on each channel data. This allows the card to process a pair of radar videos
ŠŠFully programmable sampling for radar ranges from 0 to derived from a single set of azimuth turning data and
500 NM with up to 16 k samples per return triggers, or else to process two separate videos derived
from two independent radars with their own trigger and
ŠŠ64-bit, 66 MHz PCI interface (32-bit on PCI version) turning data.
ŠŠBoard-support library with Linux and Windows drivers
ŠŠSupported by RVP for radar tracking, plot extraction and Capture of the video data into fixed-length returns is
radar video distribution applications initiated by the radar’s trigger (sync) signal. Data capture
starts at a programmable delay from the active edge of the
trigger, with video data processed in range and azimuth
to combine multiple samples and returns. In range, the
card samples video at up to 50 MHz, reducing the data
down to a defined number of samples per return to match
