Description

  • Define the architecture and system-level requirements of an airborne Emitter Location System.
  • Translate operational emitter-detection and geolocation needs into measurable technical requirements.
  • Develop and assess antenna-array concepts for airborne direction finding.
  • Define the number, type, geometry, orientation, and placement of antenna elements on the aircraft.
  • Analyse array performance across the required frequency range.
  • Assess the impact of element spacing, array aperture, phase-centre stability, mutual coupling, airframe shadowing, structural blockage, reflections, multipath, installation-induced amplitude and phase errors, and polarisation mismatch.
  • Develop calibration concepts for antenna, RF-channel, and installation-related errors.
  • Define requirements for coherent multichannel RF reception, channel synchronisation, phase matching, amplitude matching, and timing accuracy.
  • Develop and evaluate direction-finding algorithms, including amplitude-comparison, phase-interferometric, correlative, monopulse, beamforming, MUSIC, ESPRIT, Capon, and related methods.
  • Develop robust Direction-of-Arrival estimation methods for dense and complex electromagnetic environments.
  • Address challenges such as multiple simultaneous emitters, co-channel signals, low signal-to-noise ratio, short-duration and low-probability-of-intercept signals, frequency-agile and pulse-agile radars, and multipath or platform-induced interference.
  • Define confidence metrics and uncertainty estimates for Direction-of-Arrival measurements.
  • Develop emitter geolocation methods using successive Direction-of-Arrival measurements and platform motion.
  • Integrate aircraft position, attitude, heading, timing, and navigation uncertainties into the emitter-location solution.
  • Define interfaces between the Emitter Location System and the Radar Warning Receiver, ESM receiver, mission computer, navigation system, and other mission-system components.
  • Develop a coherent system concept in which the Radar Warning Receiver and Emitter Location System share receiver resources, detections, signal descriptors, tracks, and threat information where appropriate.
  • Assess trade-offs between wideband threat warning, accurate direction finding, emitter identification, and geolocation performance.
  • Define latency, update-rate, probability-of-intercept, dynamic-range, sensitivity, and accuracy requirements.
  • Develop simulation environments and representative test scenarios for evaluating array and algorithm performance.
  • Perform Monte Carlo analyses and sensitivity studies for antenna-placement errors, RF imperfections, navigation errors, and emitter geometries.
  • Support hardware-in-the-loop testing, antenna-range testing, calibration campaigns, ground testing, and flight-test activities.
  • Define verification and validation methods for direction-finding and emitter-location performance.
  • Coordinate closely with antenna, RF, ESM, Radar Warning Receiver, navigation, software, aircraft, and mission-system engineering teams.

Requirements

  • Degree in electrical engineering, communications engineering, physics, aerospace engineering, mathematics, or a related technical discipline.
  • Several years of professional experience in one or more of the following areas: direction finding, emitter location, Radar Warning Receivers, Electronic Support Measures, radar signal processing, phased arrays or antenna arrays, or multichannel coherent RF systems.
  • Strong understanding of antenna-array theory, array manifolds, phase differences, amplitude patterns, beamforming, grating lobes, and angular ambiguity.
  • Experience with airborne antenna placement and platform-installation effects is highly desirable.
  • Strong understanding of Direction-of-Arrival estimation algorithms and their practical limitations.
  • Experience with phase-interferometric or amplitude-comparison direction-finding systems.
  • Familiarity with high-resolution subspace methods such as MUSIC or ESPRIT is beneficial.
  • Understanding of radar and Electronic Support signal characteristics, including pulse, frequency, modulation, scan, and waveform parameters.
  • Experience with Radar Warning Receiver or ESM architectures, including detection, pulse measurement, deinterleaving, identification, threat evaluation, and tracking.
  • Understanding of the trade-offs between RWR warning performance and precision emitter-location performance.
  • Familiarity with geolocation, state estimation, sensor fusion, and navigation-error propagation.
  • Experience defining requirements and interfaces for complex airborne mission systems.
  • Experience with electromagnetic simulation tools such as CST, HFSS, FEKO, or comparable tools is beneficial.
  • Experience with real-time embedded signal-processing systems, FPGA-based processing, or heterogeneous compute platforms is desirable.
  • Strong analytical, communication, and technical-documentation skills.
  • Ability to work across antenna, RF, signal-processing, software, navigation, and aircraft-integration disciplines.

Benefits

  • Competitive salary and VSOP options.
  • Relocation support up to €2,500 and 4 weeks of temporary accommodation.
  • €500/£450 yearly learning allowance.
  • Gym membership and mental health support through Nilo.health.
  • Regular company events and monthly social allowances.
  • Enhanced parental leave: 22 weeks fully paid for primary caregivers and 6 weeks for secondary caregivers.
  • 5 days of paid family emergency leave, plus a 100% remote work option during pregnancy and a phased return to work.
  • Hands-on onboarding program with early cross-team work and tooling/application development opportunities.
