RF Integration & Compatibility

RF Integration & Compatibility

The ever increasing number of RF and electronic systems being integrated onto platforms, fixed sites, and even personnel, presents platform managers and system integrators with major challenges in ensuring that collocated systems can operate effectively without suffering or causing interference.

Phasor Innovation has expertise and experience in design, analysis and problem-solving related to all aspects of complex system integration and RF compatibility.

Platform Integration

The Phasor team has proven experience successfully integrating C4I and FP ECM subsystems onto military platforms (soldiers/vehicles/aircraft/ships/fixed sites). To achieve successful platform interoperability requires careful planning and detailed analysis to ensure the overall system and sub-systems meet there defined specification and operational requirements.

The Phasor team can guide customers on the best practices in areas such as shielding, grounding and bonding,filtering, equipment/antenna/cable layouts to reduce interoperability risks and comply with relevant Interoperability, EMI/EMC, Grounding & Bonding, Lightning and TEMPEST standards.

RF Compatibility

RF Compatibility encompasses all aspects of the electromagnetic compatibility of antenna connected sub-systems. Phasor Innovation has a strong background in RF compatibility, including application of the key standards used by the US, UK and Australia (MIL-STD-464 and DEF STAN 59-411). The Phasor team has proven experience conducting RF Interoperability testing, simulation and analysis. We can work with our customers to assess the RF compatibility of sub-systems such as radio communications, radar, FP ECM and EW systems against operational and performance requirements. The Phasor team can assist with requirements analysis, design, testing, simulation and analysis for RF Compatibility for any system or platform.

Co-Site Interference

A particularly challenging system integration problem is the prediction, analysis and management of interference between multiple RF systems integrated together onto a single platform or site. The challenge is becoming ever greater as operating frequencies and bandwidths of RF systems increase. Co-site interference often occurs between transmitters and receivers used for communications, FP ECM, EW, GPS and radar. The wide-band nature of many of these systems means that the potential for interference from overlapping frequency bands and transmitter harmonics
and spurious emissions is highly complex.
Phasor Innovation has the expertise and tools to analyse, predict and optimize RF co-site performance by applying state-of-the-art measurement, simulation and analysis techniques. Our comprehensive co-site analyses take into account a large number of contributing factors, such as:

  • Real-world transmitter emissions
  • Harmonics, spurious and phase-noise
  • Antenna coupling
  • Platform effects
  • Multi-path propagation
  • Non-linear receiver characteristics
  • Sensitivity and range requirements
  • Operational requirements

By analyzing these and other data, Phasor can build a comprehensive source/victim matrix to determine system performance impacts over the entire frequency range of interest. Various parameters can then be adjusted to optimize performance.
