Overview

Objective :

General objective

Passive and active radio-frequency (RF) systems in general and surveillance radar systems in particular remain vital assets for supporting multi-domain operations: incl. air and air defence missions, as well as ground/maritime operations.

Management of the electromagnetic spectrum has increased in importance. Radar operation must be compatible with other communication and control systems running concurrently. Management of emission and sensing in both space and frequency increases the systems covertness. It also improves the system’s ability to discriminate reliably signals coming from passive and civilian sources as well as active disturbances such as jammers and decoys.

Emerging technologies lead to the increased appearance of threats that are difficult to detect and track due to their low radar cross-section (RCS) (e.g., stealth technologies), manoeuvring characteristics (e.g., hypersonic weapon systems, slow-moving airborne units) or saturation attack tactics. Facing such a wide spectrum of threats (in terms of variation of speed, angle of approach and altitude), existing surveillance systems are reaching their limits in terms of detection range, angular domain coverage, and tracking capabilities. Specific operating modes (e.g., multistatic configurations) can improve detection and tracking performance. They however lead to an increased requirement on multiple beams forming. Proper detection, recognition and classification of different targets in a variety of operational conditions also requires a finely tuneable band.

Specific objective

Those operational and technical challenges can be met by future systems with:

  • agile digital beamforming to optimise observation time, volume coverage and detection reliability
  • System characteristics such as wide or ultra-wide band coverage, low noise, high coherence
  • Software defined waveforms with high degree of flexibility and use of multiple bands
  • Data processing functions to enhance detection performance, target recognition and classification, notably with respect to new threats

In order to be operated in various conditions and to be integrated in various platform, specific requirements moreover apply to the dimensions, weight and energy consumption of the radar modules (e.g., through miniaturization or grouping of functions in small electronic units) as well as their materials and electronics design to ensure optimal operability in harsh conditions. Efforts are also aiming at integrating multiple functions (radar, communication, electronic warfare) in a single radio frequency system for multi-role systems (e.g., see call PADR-EMS-03-2019).

Scope and types of activities

Scope

Recent research and development efforts in the field of radar and electronic warfare systems have the goal to create more flexible and adaptive systems in terms of modes of operation and beamforming. At the same time, new technologies offer possibilities to explore different frequency (or bandwidth) ranges while maintaining a high signal-to-noise ratio. A further objective is to integrate more functions, including internal computing capacities, while responding to the operational restrictions in terms of size, weight and power consumption and cost (SWaP-C).

The scope of this call topic focusses on electronic components and their integration that help to accomplish the above-mentioned goals by achieving:

  • improved size/weight/power ratios through miniaturisation and system integration
  • Integration of new technologies to increase the system’s adaptability to environments and operational scenarios.
  • Demonstration of agile and precise radar beam steering and detection performance.

The following enabling technologies serve as examples for the improvement and integration scope of this topic, without excluding other relevant technologies:

  • direct sampling technologies able to perform data conversion in any radar frequency band, reducing the RF front-end complexity and maximizing the miniaturisation;
  • hardware and software components for digital beamforming, including using photonic components, that enable generic and reconfigurable digital beamforming, especially with true-time delay, broadband characteristics, multi-beam capability;
  • Hardware and software that would allow real time signal and data processing coming from digitized received signals at radiating element level in order to extract and store the information on targets including detection, tracking and classification;
  • Components that enable the generation of extremely stable radio-frequency signals
  • Antenna components that emit in a broad frequency band with low spurious emissions to adapt to the environment, e.g., by exploring fully polarimetric active electronically scanned array (AESA) antennas which are more robust against interferences and can enable enhanced performance in terms of detection and classification.

Proposals should target a substantial technological advancement in order to bring the considered components to a maturity level corresponding to laboratory testing or higher (technology readiness level TRL> 4).

Furthermore, proposals may include complementary aspects on:

  • application of artificial intelligence as a means of enhancing target detection, classification and identification performance, notably with regards to new threats, including to enable cognitive radar concepts.
  • Integration aspects (such as interfaces with other sub-subsystems and data exchange formats) including high data rate transfer to other sub-systems (software and/or hardware aspects), in particular enabling distributed radar setup and Command and Control integration

This topic complements past and ongoing research and technology efforts supported by the EU, e.g., through the calls PADR-EMS-03-2019, PADR-EDT-02-2018 and the calls EDF-2021-SENS-R-RADAR, EDF-2021-MATCOMP-R-RF as well as Member States’ and Norway’s efforts, including in the EDA framework.
