Modular RF Systems for Operations & Experimentation

Two products, one family. Lark is a programmable RF node for spectrum sensing, active/passive radar, radar deception, and channel emulation. Vantage is a programmable reflective signature surface for target emulation and propagation control. Dual-band across 80 GHz and 60 GHz, supported by Lumen, a simulation operations platform, and a cryogenic RF research line.

Lark — Programmable RF Node
HardwareSoftware80 / 60 GHz

A field-deployable, distributed RF node built around mature mmWave radar hardware. Lark consolidates four capabilities into a single platform (spectrum sensing, active/passive radar, radar deception, and channel emulation) purpose-built for operations and experimentation in dense, short-range RF environments. Lark-80 targets the 80 GHz radar ecosystem; Lark-60 extends into the 60 GHz communications band.

Capabilities
  • Spectrum sensing: wideband monitoring and spectrum awareness
  • Active and passive radar: distributed, multi-node operation
  • Radar deception: programmable delay, false-target and signature emulation
  • Channel emulation: programmable multipath, Doppler, and propagation effects
  • Open-architecture data interfaces and standard control APIs
  • Multi-node synchronization for distributed configurations
Applications

Radar test and calibration. Active and passive sensor experimentation. Distributed radar research. Spectrum monitoring and RFI characterization. Academic and laboratory mmWave research.

Vantage — Programmable Reflective Signature Surface
HardwareSoftware80 / 60 GHz

A modular, programmable passive or semi-passive metasurface that dynamically shifts the phase, amplitude, and polarization of incident RF waves. Vantage delivers programmable RCS, target emulation, and propagation control through a thin, conformable, zero-emission surface. Vantage-80 anchors the 80 GHz radar-signature regime; Vantage-60 extends into 60 GHz reconfigurable-surface channel shaping.

Capabilities
  • Programmable radar cross section across the operating band
  • Passive signature control: zero RF emissions, no active transmit chain
  • Target emulation: repeatable, calibrated reflective signatures
  • Propagation shaping: multipath, beam steering, channel manipulation
  • Thin, conformable, low-power form factor
  • Calibrated profiles for laboratory and field test
Applications

Automotive radar test and calibration. Programmable RCS references for test ranges. Radar target emulation and signature management. Reconfigurable surface research for advanced communications. Academic and laboratory mmWave research.

Ultrawideband Cryogenic Oscillators
Research Line

Ridgefield develops ultrawideband cryogenic oscillators engineered to operate at millikelvin temperatures. The oscillators serve as local oscillators, signal references, and pump sources inside quantum control and readout chains, replacing room-temperature RF sources that today drive thermal load and interconnect complexity at the cold stage.

Targeting integration partners building parametric amplifier systems, cryogenic measurement infrastructure, and scaled quantum architectures where cryogenic-native sources reduce thermal load, simplify interconnects, and improve system performance.

Applications

Quantum control and readout. High-performance FMCW radar.
