PATHFINDER/ST ARPA: 34-cm or 25-cm

PPIs (16" or 12" diagonal CRT IMO equivalents) provide automatic tracking of up to 40 targets with vectors and readouts for the most dangerous 20. Have auto and manual acquisition, and unique trial maneuvers.

PATHFINDER/ST TM/EP: 34-cm or 25-cm

PPIs (16" or 12" diagonal CRT IMO equivalents) have True and Relative

Motion displays. Electronic Plotting, course, speed, bearing, range, CPA, and

TCPA for two selected targets.

Enhanced Navigation

Package (ENP). The

Best Is Now Better.

The Enhanced Navigation Package (ENP) is the latest innovation to the

PATHFINDEFi/ST ARPA and TM Radar.

ENP adds significant navigational and operational features that keep the

PATHFINDER/ST raster display at the forefront of industry design. All Raytheon

PATHFINDER/ST systems now offer ENP as standard supply, and systems already in use can be easily upgraded.

The PATHFINDER/ST raster display with ENP includes a navigation sensor interface, stored Navline maps (ARPA only), new "pop-up" menu operation, and configurable serial data output ports.

Navigation sensor input can accept NMEA sentence structure from conventional sen- sors such as differential GPS, GPS, or

LORAN-C. A second input port is available that will accept information from a Syledis precision positioning system. The naviga- tion sensor is used to position and stabilize

Navline maps on the PATHFINDER/ST

ARPA display.

Operation of the PATHFINDER/ST ENP is simplified by the "pop-up" menus. Three main menus are: MAPS, OPERATE, and

ARPA. The MAPS page is used to save, retrieve, edit, and control Navline maps.

The OPERATE page contains operational functions such as: Vector Selection; Trial

Maneuver, and Course Up. The ARPA page allows selection of features such as

Collision Assessment Mode, Auto Drift, and Auto Acquisition.

Comparison Tests

Prove PATHFINDER/ST

Radars See What

Others Can't.

In side-by-side comparison tests, a

PATHFINDER/ST display and a conven- tional radar display were connected to the same radar system. PATHFINDER/ST consistently displayed targets not detect- ed by the conventional display.

Simple Installation and Flexible System

Configuration.

PATHFINDER/ST Radars satisfy a very wide range of installation and operating requirements. Signal multiplexing reduces connections between PATHFINDER/ST receivers and displays. This, combined with electronic interswitching for dual systems, the ability to mount transceivers "up" in antenna pedestals, or "down" in separate cabinets, and keyboard entry of all setup parameters, makes any installa- tion straightforward, simple, and economi- cal. In addition to having the optional IMO- required, antenna-mounted performance monitors, PATHFINDER/ST Radar software provides menus for extensive self-testing of virtually every function.

Unmatched

Target Detection.

Using increased signal-to-noise levels, high dynamic range, precisely matched pulse bandwidths, and exclusive Rain

Rate circuits, PATHFINDER/ST receivers faithfully capture target returns even in severe clutter.

PATHFINDER/ST multistage processing analyzes, compares, tests, and samples the received signal so that all detected targets, no matter how weak in signal strength, are distinguished from clutter and clearly displayed.

From the control panels through the computer, transmitter, and receiver- and then in five steps leading to the

CRT-Raytheon's exclusive Superior

Technology provides sharp, bright radar pictures virtually free of clutter.

As we constantly strive to improve Raytheon products, all specifications are subject to change without notice.
