HPx-700 Radar Input & Processing Unit

The HPx-700 is primarily available as a small form factor unit in a standalone case (with an external mains PSU). However, for OEM customers, it is also available in a board-only form factor.

The HPx-700’s onboard Broadcom BCM2712 64-bit ARM processor supports embedded versions of Cambridge Pixel’s family of SPx software modules. The processor features a quad core Cortex-A76 (ARMv8) 64-bit System-on-Chip (SoC) and has guaranteed production through to 2035. A wide range of system functions are supported by the HPx-700, including combinations of:

• Primary radar digitisation and network distribution/streaming
• Radar plot extraction (including IFF processing)
• Radar target tracking
• Radar stream record/replay
• Fusion of radar streams

The HPx-700 includes a flexible radar hardware interface that is pin-compatible with Cambridge Pixel’s existing HPx-410 PCIe card.

The 37-way radar input connector supports dual radar channel operation and interfaces with RS-422, single-ended or open-collector signal types for maximum compatibility. It accepts radar video, trigger and azimuth signals in the form of ACP/ARP or serial data.

Backwards compatibility with the HPx-410 gives access to a wide array of pre-built radar interface cables, alongside detailed Engineering Application Notes which guide the integrator on how to interface to specific makes and models of radar. The range of cables includes various generic signal breakout cables, as well as radarspecific cables for a diverse range of radars from: Consilium, Furuno, JRC, Kelvin Hughes, Koden, Sperry Marine, STN Atlas and Terma.

The HPx-700 includes an embedded version of Cambridge Pixel’s proven SPx Server software. As standard, there are three main versions of the product, each of which progressively adds additional processing functionality:

• HPx-700 Distribution – includes primary radar digitisation and
• network streaming
• HPx-700 Detection – adds both plot extraction and proximity
• detection processing
• HPx-700 Tracking – offers a complete multi-hypothesis primary
• radar tracking solution

Optional features such as radar stream record/replay, sensor fusion and IFF processing can be provisioned through the purchase of additional software runtime licenses.

Configuration of the HPx-700 is achieved either through the built-in web GUI or by editing human-readable configuration files. The web GUI can also be used to update the unit's functionality and provision optional features at a later date.

The HPx-700 includes dual RJ45 Gigabit Ethernet interfaces, which are used for web GUI control connections and for distributing radar video, plot reports and track reports.

A variety of video, plot and track report formats are supported, including Cambridge Pixel’s SPx format and numerous categories of Eurocontrol’s ASTERIX format as well as NMEA 0183 TTM messages.

Additional I/O is provided in the form of a USB Type-A connector on the front panel.
