Technology Overview

A Sophisticated Novel Radar Sensing Configuration

aiRadar research radar’s with the aiRPL Software EcoSystem provides a low‐cost production application research platform upon which highly sophisticated novel radar sensing configurations and solutions can be developed and verified by customers without having to commit to a particular and costly custom radar design. It provides a platform upon which customers can figure out what the radar needs to adaptively transmit, how it should receive, how it should process the receive data and what to do with the processed data.

Further, it allows customers to evaluate how much radar hardware they need and how it should be configured to get the data they need. Customers can develop their own proprietary IP encapsulated within aiRPL that solves their sensing challenge. Everything from how the radar operates to how the hardware is configured can be captured within aiRPL constructs. Then, a  complete custom aiRadar system can be procured, or if a customer chooses they can licence the FPGA IP cores, with the aiRPL Command Processor and the aiRPL Processing Unit, purchase engineering support  and download their encapsulated IP directly into their new custom radar.

Customers can license the aiRadar Ecosystem (aiRPL Integrated Software Development Environment and aiRPL Databases ) to evolve, sustain and advance their application specific radar and its derivatives.

Radar Technology

A typical aiRadar research radar is the RRI‐400 (Research Radar Interferometer). This is a truly Massive Multi‐Input Multi‐Output (MIMO) System with 48 independently programmable Transmit Receive Modules (TRMs), a total of 1536 Phased Array Elements in an AESA with Hybrid Analog/Digital Beamforming arranged as a Triple Baseline Interferometer (3D) with 16 Digital Azimuthal Apertures. Operated at a typical frequency of 66GHz, the 592mm long azimuth aperture can produce two way azimuth resolutions of better than 0.25°, with an azimuth scan coverage of 90°.

The RRI‐400 may be configured as:

  1. a Real Aperture Electronically Scanned Radar with 64 or 128 beams,
  2. a simple single beam Synthetic Aperture Radar, or
  3. a 16 Azimuth Aperture Synthetic Aperture Radar with real‐time cotemporaneous Digital Surface Model (DSM) generation, and cotemporaneous multiple baseline Ground Moving Target Indication (GMTI).

The RRI series of radars are “multi-mission” software defined research radars.

The RRI series of research radars are based on our “SEM Module”. Each SEM Module has 3 rows of 4 TRM’s making a Tx/Rx array with 64 elements in the triple baseline interferometric configuration.

Modules can be tiled to suit your needs. Typically, 1, 2 or 4 modules are arrayed yielding our RRI‐100, RRI‐200 and our RRI‐400. Instruments respectively.

Our Radar ecosystem combines:

  1. Easy to use radar programming language, aiRPL.
  2. Our database, aiRDB,
  3. Our radar language compiler, aiRLC, and
  4. Our radar operating system composed of our Command Processor, our aiRPU (Radar Processing Unit) IP cores for FPGA’s.
  5. Our sensor electronics architecture.

There is a wide spectrum of radar solutions to very difficult problems. aiRadars’ business proposition trades significant technical risks in exchange for licensing fees.  We provide you with the tools to solve these problems rapidly, develop products rapidly, and get to market rapidly. All of your program’s systems will have been validated and verified on aiRadars’ proven standardized hardware and software platforms avoiding a build from scratch effort and all the risk that entails.  Developing AESA radars has never been easier.
