Wireless Data-Acquisition System for Testing Rocket Engines
A prototype wireless data-acquisition system has been developed as a potential replacement for a wired data-acquisition system heretofore used in testing rocket engines. The traditional use of wires to connect sensors, signal-conditioning circuits, and data acquisition circuitry is...
Briefs: Electronics & Computers
A facility that includes a probe station and a scanning open-ended waveguide probe for measuring near electromagnetic fields (see figure) has been added to Glen Research Center's suite...

Computing for Aiming a Spaceborne Bistatic-Radar Transmitter
BISTAT is a computer program for use in aiming a spaceborne bistatic-radar transmitting antenna at a remote planet that has an atmosphere, such that after refraction by the atmosphere and reflection from the surface of the planet, the radar signal travels toward a receiver on Earth....

A single-chip CMOS-based (complementary-metal-oxide-semi-conductor-based) transmit/receive (T/R) module is being developed for L-band radar systems. Previous T/R module implementations required multiple chips...
Briefs: RF & Microwave Electronics
Inexpensive, lightweight array antennas on flexible substrates are under development to satisfy a need for large-aperture antennas that can be stored compactly during transport and deployed to full size...
Briefs: Manufacturing & Prototyping
A horn antenna (see Figure 1) has been developed to satisfy requirements specific to its use as an essential component of a high-efficiency Ka-band amplifier: The combination of the horn antenna and an...
Briefs: RF & Microwave Electronics
An improved suspended-patch antenna has been designed to operate at a frequency of about 23 GHz with linear polarization and to be one of four identical antennas in a rectangular array. The...
Briefs: RF & Microwave Electronics
A finned-ladder structure has been invented in an effort to improve the design of the slow-wave circuit of a traveling-wave tube (TWT). The point of departure for the design effort was a prototype TWT...
Briefs: RF & Microwave Electronics
A method of estimating the pointing error of an offset-conic-section reflector antenna equipped to receive in both right circular polarization (RCP) and left circular polarization (LCP)...
Briefs: Electronics & Computers
Three coplanar-stripline circuits have been designed to perform coupling and filtering functions in microwave systems. These circuits could be incorporated into feed networks for microwave...
