Racon; Radar Target Enhancer (Rte) - Furuno FAR-3210 Operator's Manual

2. RADAR, CHART RADAR OPERATION
Shadow sectors
Funnels, stacks, masts, or derricks in the path of the antenna block the radar beam. If
the angle subtended at the antenna is more than a few degrees, a non-detecting sec-
tor may be produced. Within this sector targets can not be detected.

RACON

A RACON is a radar beacon which emits radar receivable signals in the radar frequen-
cy spectrum (X- or S-band). There are several signal formats; in general, the RACON
signal appears on the radar screen as a rectangular echo originating at a point just
beyond the position of the radar beacon. It has a Morse coded pattern. Note that the
position on the radar display is not accurate.

Radar Target Enhancer (RTE)

An RTE is a radar transponder that is mounted on navigation buoys and masts of
small crafts to significantly improve their detection by radar. Unlike a SART or RA-
CON, which are passive, the RTE receives a radar signal, amplifies it and re-transmits
it, with the intention of making the target's signal look larger on a radar display. The
RTE can be detected on both X-band and S-band radars.
