Radar and Measurement Technology

Cheetah CheetahThe Cheetah is a hardware-gated PNA measurement system that leverages widely commercialized network analyzer technology to yield exceptional value. It provides state-of-the-art measurement sensitivity at practical speeds and a very affordable price.

Cheetah systems are turn-key and based on a total system design approach that addresses the many nuances required to achieve accurate and reliable RCS data. The versatile Cheetah architecture supports custom frequency bands in the range of 10 MHz to >100 GHz. The turn-key system integrates a PNA with a gated transceiver unit, software, a PC, and other options including antennas and target control equipment. Onsite training and an extended warranty are also provided.

Transceiver Advantage
The gated Cheetah transceiver dramatically enhances the ability of a PNA to collect RCS and antenna data. The transceiver incorporates low noise amplifiers that improve measurement sensitivity by more than 30 dB (compared to measurements using a standalone PNA). The transceiver also incorporates high isolation gating switches that preserve the PNA's dynamic range. An integrated timing unit enables precise range gating and clutter suppression during RCS measurements.
Measurement Software
The Cheetah supports both RCS and antenna measurements. Full featured software for both applications is provided by CompuQuest, a trusted and well-established name within RCS and antenna measurement communities. (For full details, please contact SPC to request Cheetah software manuals.)
