Directed Energy Weapons
High-energy Lasers
Laser-based directed energy weapons engage enemy targets with concentrated, narrow beams of energy. These powerful, precision strikes disable or destroy a target’s most critical components.
High-energy lasers (HEL) are vulnerable to complex challenges such as Stimulated Brillouin Scattering (SBS), where reflected energy can damage laser components and limit output power. From the lab to integration into deployment-ready systems, Maury additive white Gaussian noise (AWGN) sources can mitigate the risks of SBS while maintaining power level requirements.

Physical layer testing throughout the RF and microwave path of mission-critical systems
Low-Earth orbit (LEO) satellite deployments are increasing due to factors such as reduced latency, enabling civil/commercial and military applications including, but not limited to, 5G and military battlefield communications. Radar systems are also used in mission-critical applications, such as identification friend or foe (IFF) that identifies targets as either friendly or hostile. To ensure reliable operation, LEO satellite networks and radar systems require very demanding test requirements.
Maury solutions are being entrusted to provide physical layer testing throughout the RF and microwave path of the uplink and downlink for radar and satellite communications systems, spanning critical test areas such as propagation delay and 5G TDD network timing, noise tolerance testing, amplifier linearity, phase noise analysis, and characterizing antenna performance.

5G TDD Latency and Timing
5G satellite networks use time division duplex (TDD) to optimize spectrum management, rapidly switching between uplink/downlink operations on the same frequency band. As of uplink/downlink handover requirements increase in complexity as applications move to higher frequencies—advanced test instruments are needed to characterize high-speed 5G TDD switch behavior.
Maury power sensors can capture this rapid performance with 3-nanosecond rise times, 100-picosecond time resolution, and the fastest measurement rate available at 100,000 per second. Maury channel emulation solutions can simulate Doppler, attenuation and signal delay across LEO, MEO, and GEO satelltie paths.
Noise Tolerance and Jitter
As more and more satellites are launched into low Earth orbit, satellite networks must contend with various communications from relay satellites and uplink/downlink stations. To ensure performance observed in the lab is replicated after deployment, satellite communications networks must be designed to operate in real-world RF interference conditions.
Maury noise generators and channel emulators can create additive white Gaussian noise (AWGN) signals that satellite network designers can inject into their unique RF uplink/downlink paths, enabling precision signal-to-noise (SNR) and carrier-to -noise (CNR) manipulation. Jitter manifests as time-domain variations of the waveform, while phase noise measures frequency instabilities. Satellite network developers can utilize Maury phase noise analyzers to test the jitter and phase noise of their satellite network.
Amplifier Linearity
Both satellite communications and radar rely on linear amplifier performance, where the fidelity of signals directly impacts dynamic range, target detection, and tracking. Nonlinearities not only distort waveforms, but leads to a degradation of system performance and mission success.
Maury power sensors deliver the capabilities needed to assess amplifier linearity with confidence. Crest factor measurements and complementary commutative distribution function (CCF) curves provide an accurate, cost-effective approach for linearity assessment. In mission-critical pulsed radar systems, fast rise times track pulse edges cleanly and accurately, wide video bandwidth captures envelope power, and fine time resolution provides essential data on narrowly shaped pulses.
Phase Noise
Satellite communication systems that utilize higher order modulation schemes, such as those used in 5G applications, increase bit rate/bandwidth. While data rates increase, so does the network’s vulnerability to symbol errors due to phase noise. In radar systems, phase noise can mask return signals, limiting a radar receiver’s ability to resolve Doppler-shifted target information. Local oscillators (LO) can be the cause of excessive phase noise if the system is experiencing poor performance/symbol errors. Maury noise generators and channel emulators can reproduce the phase noise generated by a system’s LOs, while Maury phase noise analysis solutions can evaluate LO phase noise performance.
Maury signal generators are ideal for LO substitution, which replaces the LO with a high-quality, extremely pure, low phase noise waveform to determine if the LO itself is the cause of performance issues within the system. LO substitution can also isolate up/downconverter chains for more accurate testing without faulty LO characteristics distorting results.
Antenna Gain
Antennas are critical components for reliably communicating information. Maury peak power sensors provide a simple, convenient method to characterize antenna performance in satellite systems. Peak power sensors can monitor the incident power of a communications signal before transmission and the portion of the signal power reflected back from the antenna. Return loss is used to measure this difference between forward power and reflected power.
Antenna pattern measurements represent an antenna’s radiation properties, or how it radiates/transmit energy into space. Patterns are typically three dimensional since antennas radiate energy in every direction to some degree. Antenna gain characterizes the directivity of the radiation pattern. With x, y, and z movements, power measurement solutions from Maury can be used to determine the intensity of pulsed or CW signals that an antenna radiates in a given direction, simplifying antenna calculations and analysis.
