Raytheon Anschütz

Appendix 1

Published Radar Characteristics

        The Raytheon Anschütz product line today comprises two basic systems: the NSC18, which appears to be based in part on components of the Pathfinder-11S described in the Raymarine section and a completely new architecture, originally described as the Pathfinder-ST/Mk2 although Raytheon Anschütz has ceased using the Pathfinder brand name; whatever its new internal designation, this new architecture forms the basis of its 'flagship' systems, the NSC25 and NSC34. There are two variants of this new Pathfinder architecture, for X and S bands respectively; each variant comes in two versions, an up-mast configuration and a down-mast configuration, with different peak power outputs for each version. In all, then, there are six variants of the electronics of the new series, and beyond this, there are two available antennas for the X-band version; the NSC18, which is no longer advertised in the company's product listing, has a different antenna, and a different peak power. This is not nearly as complex as some manufacturers' product lines documented elsewhere in this handbook, even though Raytheon Anschütz may possibly have inherited the longest tradition in MNR manufacture. The technical characteristics of the present-day systems are summarized in the following tables. It should be noted that there are many examples of JRC-designed and manufactured marine radars bearing the Raytheon logo; these are not included in the tables

Antenna Characteristics versus Scan Rate

        Pulse-duration versus pulse-rate barely merits tabulation for this manufacturer, since all of the NSC25/34 systems are documented with the same values and the NSC18 apparently has only one pulse-rate. The documented values are as follows:
