HPx-410 PCIe Radar Interface Card

Overview

The HPx-410 is a direct replacement for the HPx-400e card and is available in x1 or x4 lane PCIe form factor. As with other cards in the HPx family, the HPx-410 interfaces to analogue or digital radar signals, and provides a flexible set of input options to handle a wide range of radar types. An onboard mixing capability allows a combination of analogue and digital inputs to be captured and combined. The HPx-410 card provides a dual set of inputs, allowing up to two independent radars to be connected to the same card.

The analogue video inputs are captured at up to 125 MHz using high precision analogue to digital converters at 12 bits resolution. The captured video can be optionally down-sampled to reduce the data rate before transfer across the PCI express bus, using high-speed DMA, at peak speeds up to 500MB/s (on the PCIe x4 variant). On the host computer, a driver and board-support library for Windows or Linux is available. Additionally, the SPx software suite is available to provide a full complement of radar processing functions including scan conversion and target tracking.

An on-board FPGA provides data processing and control and offers capability for expanding the data processing functions for customised applications.
