HPx-346 Analogue to Network Radar Video Converter

HPx-346 Card

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.

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.

Radar Capture

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.

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.

Network Distribution

The digitised radar video samples are formed into UDP packets, automatically fragmented if required. The video samples may optionally be compressed, using lossless compression, in order to save network bandwidth without losing information. The resultant UDP packets are then output on a standard RJ45 Ethernet connector, under control of the on-board ARM processor.

Radar returns are processed and distributed as they are captured, ensuring low latency between capture and distribution. Open standards, such as ASTERIX CAT240, are supported for the radar video data output onto the network. So this data may be received and decoded with no special software requirements. However, the full power and flexibility of the SPx software is also available to receive and process this data.


The HPx-346 unit is configured, controlled and monitored by a convenient and intuitive web interface. No programming is required, simply point a standard web browser at the appropriate IP address and port number and an easy-to-use configuration page is presented.

Purchase Options

The HPx-346 is commonly supplied as a small box-level unit but is also available as an OEM card for system integrators to embed within their own systems. Additionally, 19" rack-mount units are available for multiple radar connections and may have customised front panel connectors.
