Real Time Signal Analyzer
Today's sophisticated weapons systems have created a signal environment so dense and complex that currently deployed signal analysis systems have become severely limited in their ability to provide accurate real-time analysis. They lack the processing speed, digitizing accuracy, memory capacity and interactive display capabilities necessary to analyze this new generation of multi-function, high data rate emitters.
The increase in weapons systems has created specialized intelligence requirements, rendering current signal analysis systems nearly obsolete. Their large size and weight, inflexible architecture and limited input/output capabilities have reduced their effectiveness against modern technology and operational doctrine. For today's commander, it is imperative to have signal analysis support that can provide strategic intelligence that is accurate and detailed, and tactical intelligence that is fast, on-line, and decisive.
HRB Systems has developed the Real Time Signal Analyzer (RTSA) to meet the demands of modern signal analysis. RTSA is a compact, modular system that performs fine grain, real-time measurements in an extremely dense radar signal environment. In tactical applications, RTSA increases the speed and accuracy of "online" signal analysis to provide real-time tactical assessments. In strategic applications, RTSA significantly reduces the task load placed on theater and national processing centers by providing signal analysts with the unique capability to interactively digitize data.
RTSA has a flexible, open architecture which makes it compatible with nearly every wide band intercept receiver. Its plug-in signal conditioning units permit RTSA to accept inputs from a variety of both detected and pre-detected sources. In heavy emitter environments, RTSA can perform time domain measurements to resolutions exceeding 001 nanoseconds at a peak rate of up to 4 million pulses per second. It also features a high resolution, interactive color display and a computer compatible digitizer.
RTSA HELPS ANALYSTS TO CLEARLY "SEE" SIGNALS OF INTEREST
RTSA`s measurement techniques combine the innate pattern recognition abilities of the operator-analyst with the high level of accuracy and resolution that can be attained only through digital signal processing.
Designed to be highly interactive and user-friendly, RTSA incorporates sophisticated signal plotting algorithms and features that greatly simplify the analysis process for the analyst: controllable cursors, an on screen alpha numerical legend, a high resolution color display, simple control and set-up menus, a printer interface and both RS-232 (for graphics and data listings) and IEEE 488 buses (for remote control of the instrument). Backed by this support, the analyst can easily conduct and document rapid, accurate signal analysis.
Variable Control Cursors
Continuously variable cursors isolate and expand segments of complex signals to facilitate detailed analysis in a number of ways. They:
· Expand or compress specific data segments, by increasing measurement accuracy and resolution · Designate specific signals for analysis, while eliminating interference from the data set. · Extract a signal for analysis or documentation by excising it from a dense environment or interferrence · Set hounds within which signal characteristics such as PRI, RF, or amplitude changes can be documented, or raw data listed.
In addition, cursor colors match the color of the data trace, and highlight cursor-signal intersection or overlap, thus eliminating parallax error.
On Screen Alphanumerics
RTSA features an on-screen alphanumeric legend which documents both signal parameters and system configuration This legend, which appears at the top of RTSA's screen, displays:
· The PRI or PRF measurement of the signal. · Full scale time on both vertical and horizontal axes.
· Time, amplitude or frequency differences between cursor boundaries. · Statistics such as mean, standard deviation, and si~e of the data set for the PRI, PW or RF measurements bounded by the horizontal and vertical cursors.
· System display status including display modes, operational modes, input modulc(s), and storage register.
· Date and time of day. · Cursor selected raw data sets.
