Providing Hardware and User-Customizable IP to Digital Radar Systems

Advanced digital radar systems that can detect targets in complex, high-clutter environments are essential for mission-critical operations such as defense, search and rescue, and offshore security. Digital radar systems provide activity monitoring, target detection and classification, guidance, and encroachment notification. Additionally, active electronically scanned (AESA) phased array digital radar systems, which reinforce antenna signals in desired directions and suppress them in others, can perform search, track, and guidance functions for scores of simultaneous targets.

New Wave DV offers radar interface card hardware compatible with XMC, VPX, PCIe, and PXIe form factors. Leave the details of the interface to New Wave DV, let your team focus on the design of the radar itself. The best part is, the hardware’s protocol IP is customizable, allowing end-users to add their own hardware-based processing to the radar interface card, reducing processor burden and latency while increasing determinism.

Embedded Radar Processing Hardware

Our embedded radar interface cards are purpose-built for extreme environments, high-bandwidth networking, and interface applications. The V1153, V1160, and V1161 XMC cards will withstand harsh environments while staying within your SWaP and budget requirements. Supporting temperature ranges from -40°C to +85°C and complying with VITA 20 standards, each XMC card delivers a reliable, long-lasting solution for your rugged embedded needs.

New Wave DV also offers cards suitable for test and measurement applications. The V1151 and V1152 XMC cards, and V5051 and V5052 PCIe cards offer the same hardware based protocol engine implementations as the embedded cards, with cost effective commercial optics replacing the rugged optics of the embedded families. The near perfect determinism of hardware based protocol engines make these cards ideally suited to test and measurement applications requiring repeatability.

Protocol support for digital radar systems includes Serial Front Panel Data Port (sFPDP), Fibre Channel Remote Direct Memory Access (FC-AE-RDMA), and 10G/25G/40G/100G Ethernet/RoCEv2. 

The sFPDP protocol offers a high-speed, low-overhead, point-to-point communication protocol commonly used in data intensive processing applications. The FC-RDMA core provides a complete layer 4 hardware IP solution for the FC–AE-RDMA protocol. The core provides full FC compliance, hardware-based LUN mapping, and complete offload of RDMA frame handling. Ethernet/RoCEv2 is implemented using a Mellanox® ConnectX®-5 network interface device, offering industry leading performance and offload functionality. 

New Wave DV also offers other Fibre Channel derivatives as COTS products, and would be interested in discussing new protocols as well.

User Customization

Give your system architect more tools for radar data processing. New Wave DV IP cores such as sFPDP and FC-AE-RDMA can include a user sandbox area, between the protocol engine, and the DMA engine. The protocol engine provides a generic packet bus to the sandbox where users can add their own RTL to pre-process data. The usermodified data is provided to the DMA engine, and ultimately seamlessly provided via New Wave DV supplied drivers to user-space. New Wave offers rich OS support for drivers and friendly customer service to help end users walk through their design

The New Wave DV V1161 offers an equivalent user modifiable solution for Ethernet/RoCEv2. The V1161 offers a Mellanox® ConnectX®-5 paired with a Xilinx Versal FPGA. The end user can use the FPGA as a “bump in the wire” to intercept and modify radar data prior to passing off to the ConnectX-5. The end user can also use the ConnectX-5 to directly receive radar data, then pass this data off to the FPGA via a peer-direct DMA transfer. The FPGA can then operate on radar data payload, and pass the modified data from the FPGA to the host processor via another peer-direct DMA transfer.

User modifiable RTL logic is a very powerful tool for system architects. A variety of pre-processing can be completed in the interface card such as down-sampling, area focus, and frequency analysis. This technique can unburden the processor from these tasks. In down-sampling and other data reduction techniques, it has the added bonus of enabling line rate bandwidth interfaces while still reducing PCIe link bandwidth, eliminating a difficult system bottleneck.

Key Features of Radar Interface Card Hardware

New Wave DV’s powerful, high-density FPGA-based card designs offer high bandwidth, low latency, highly deterministic interfaces that can be customized by end users.
