Analogue Radar to Network Distribution

The HPx-346 is a small form factor, combined analogue radar input and network radar video distribution unit. The unit connects to the analogue video interface on a radar, digitises the data and distributes it as UDP packets over Ethernet.

Latest Signal Input Design

The HPx-346 uses the latest signal input design and 100 MHz sampling.

The HPx-346 accepts radar video, trigger and azimuth signals in the form of ACP/ARP pulses. A wide variety of signal types and input voltages are supported, allowing the unit to be connected to many different radar models.

Unlike more basic hardware offerings, the HPx-346 includes easily adjustable resolution and sampling range, giving the user full control.

Network Output in Open Standards

The digitised radar video samples are formed into UDP packets, automatically fragmented if required.

The option to compress video samples, using lossless compression to save bandwidth without data loss, is also included.

Supports open standards, such as ASTERIX CAT-240, for the radar video data so it can be received and decoded with no special software requirements.

The HPx-346 is also fully supported by the optional SPx software and SPx Development Library.

Web Interface for Easy Control

A favourite feature among customers is the convenient, easy-to-use, built-in web interface, allowing the unit’s operation to be configured.

As with the radar video data format, the format of the control messages is published, allowing external code full control of the unit. This allows the hardware status to be monitored by connected monitoring software such as SPx Monitor.

Alternatively, the SPx Development Library is available to provide a convenient C++/C#/Java control class.

Boxed, Rack-mount, OEM Card & Dual-redundant Versions

In addition to the standard, small-form factor box, the HPx-346 is also available in a dual card variant as a 19" rack enclosure, and as a card for OEM applications. Front or rear panel connectors on the 19" rack version can be customised.

A dual-redundant network version, the HPx-346D, provides two independent Ethernet interfaces to send network radar video simultaneously onto two networks.

Radar Video to ASTERIX CAT-240 Converter

The HPx-346 can output radar video in the ASTERIX CAT-240 open standard and other formats.

Fast, Low Power

The HPx-346 features a SoC (System on Chip) to process the digitised radar video samples and packetise them ready for distribution over the unit's Ethernet port. The SoC is fast to boot and is operational within 10 seconds of power-up. The unit is extremely low power, using less than 5W peak, meaning that it can readily be accommodated with no special cooling requirements in most environments.

Widely Compatible

The HPx-346 accepts radar video, trigger and azimuth (ACP/ARP) signals as its input from the radar. It can be configured to handle a wide range of signal types, including differential and single-ended with signals up to 60V, allowing it to be connected to many different radar models.

High Precision

The analogue input video is captured at up to 100MHz sample rate, using a high-precision analogue to digital converter at high resolution. Radars with PRFs up to 16kHz and rotation rates up to 120rpm may be supported by the card.
