Mi-Wave’s Trihedral Corner Reflectors are precision-engineered passive radar targets designed for radar calibration, radar cross section (RCS) measurement, antenna testing, and RF system verification. Constructed from three mutually perpendicular reflective surfaces, these reflectors provide a strong, predictable signal return by reflecting incident RF energy directly back toward the source.
Available in a range of sizes and configurations, Mi-Wave trihedral corner reflectors are suitable for use across RF, microwave, and millimeter-wave frequency bands. Their stable mechanical design and repeatable electromagnetic performance make them ideal for both laboratory environments and outdoor test ranges.
Note: The trihedral corner reflectors shown represent only a portion of Mi-Wave’s capabilities. Custom reflector designs are available to support specific frequency ranges, performance requirements, and application needs.

Why Choose Mi-Wave for Trihedral Corner Reflectors
Proven RF and Radar Calibration Expertise
Mi-Wave has decades of experience designing and manufacturing high-performance RF, microwave, and millimeter-wave components used in demanding test, measurement, and calibration applications. Our trihedral corner reflectors are built to deliver consistent and repeatable results for critical radar testing.
Reliable Passive Retroreflection
Trihedral corner reflectors are passive devices that require no power or active electronics. Their geometric design ensures a strong and stable radar return over a wide range of incident angles, making them highly effective reference targets for system calibration and performance verification.
Precision Construction
Each reflector is fabricated with tight mechanical tolerances to maintain proper alignment of the reflective surfaces. This precision ensures predictable radar cross section behavior and accurate test results across a wide frequency range.
Custom Reflector Solutions
In addition to standard designs, Mi-Wave offers custom trihedral corner reflectors tailored to specific frequency bands, size requirements, mounting configurations, or test environments. Our engineering team can support unique radar and RF test applications.
What This Product Does
Passive RF and Microwave Retroreflection
Trihedral corner reflectors function by reflecting incident RF, microwave, or millimeter-wave signals off three perpendicular surfaces, returning the signal directly back toward the transmitter. This multi-reflection mechanism produces a strong backscatter response with consistent amplitude and phase characteristics.
Because the reflected signal is highly predictable, trihedral corner reflectors are commonly used as reference targets for validating radar system performance, antenna alignment, receiver sensitivity, signal processing accuracy, and overall system stability.
Typical Uses and Applications
Trihedral corner reflectors are widely used in:
-
Radar system calibration and validation
-
Radar cross section (RCS) measurement
-
Antenna pattern and gain testing
-
RF, microwave, and millimeter-wave test setups
-
Target simulation for radar performance evaluation
-
Laboratory measurements and outdoor test ranges
-
Aerospace, defense, and communications system testing
These reflectors provide repeatable and reliable signal returns, enabling accurate benchmarking and performance comparison across different systems and test conditions.
