    | X-Band Two-Unit Systems | LARGE MARINE RADAR JMA-6252 3cm, 6/9ft, 25kW, 21-in, 120nm C Vallee tiie Ma emai @ Easy-To-See Bright Raster-Scan Display @ Suited for Any Vessel Type, Small or Large a LKR The JMA-625: a two-unit radar system offering accurate navigational informa- tion and displays on short to long ranges, and incorporating various new features such as increased navigational data inputs, high-definition, high-resolution raster-scan sisplay, newest radar signal processing, and ship's trail display. JMA-6252-6 _| X-band two-unit 25kW radar with 6-foot scanner unit JMA-6252-9 | X-band two-unit 25kW radar with @-foot scanner unit FEATURES @ High-Resolution Raster-Scan CRT Display ‘The 21-inch high-resolution raster-scan flat CRT screen provides bright easy-to-see displays, ensuring ease and efficiency of ship operation. Newest Radar Signal Processing The adoption of a microwave IC(MIC) frontend and the most advanced video signal processing technology permits the radar to clearly detect even weak signals from targets on long ranges. @Ship’s Trait Display A moving target’s trail can be displayed on the video screen, its direction and length presenting the target’ course and speed, This function is helpful in ship operation and collision avoidance. ‘Simple Operation ‘The operating panel is designed for ease of operation by using electronic touchkeys in different colors and a trackball, enabling the operator to take fast actions in case of emergency. Various Radar Video Modes Radar video is presented in True/Relative Motion mode and bearing presentation is available in North- Up, Head-Up and Course-Up modes. © Self-Testing Facilities The operational status of the entire system is stead ily monitored by a system monitor to make it to demon ‘ate 100% of the functions. If a function deteriorates, sual blinking alarm appears on the CRT screen with an audible alarm, System function tests can easily be made during normal operation. @ Useful Naviine Display Navlines can be displayed on the radar video and stored in memory as course or exclusion lines for effective use for coastal navigation. Navlines are use- ful to monitor own ship's position relative to a planned route on the display Speedy Cursor Movement by Trackball The cursor position can be moved easily with the trackball, ensuring speedy bearing and dis urements. Electronic Cursor (EBL) Electronic Bearing Line can be presented in the ‘TER mode in which it originates from the radar video center (own ship's position) and in the INDEPEN DENT mode in which it originates from the cursor mark of the trackball, Used with the VRM (variable range mark), the bearing and distance between two points can be measured easily. ‘Electronic Parallel Cursors Electronic parallel lines can be presented on a radar video, ensuring effective use in observing the positions of other ships relative to own ship. z = Danger Alarms by Guard Rings Guard ring can be freely set and displayed on the video screen; the variable is presettable by the track ball. Audible and visua) alarms are given when a target is on this ring, alerting to a collision risk, stranding, or watchkeeping. eort. The radar video can be freely off-centered up to approximately 65% of its radius, presenting more infor mation on own ship's surroundings fore and aft. ©X2 Enlarge The radar video can be enlarged up double so that very small targets can be expanded so as to be easier to see. ‘© Digital Display of True Bearing ‘The built-in NSK (north stabilizing kit) of electronic type, but using no repeater motor, makes the radar compatible with aay type of gyro compass by simple swith operation, Own ship’s true bearing is digitally displayed on the screen at all times, contributing to efficient ship operation. ‘Own Ship’s Track (Only when navigation unit is uned) own ship's track can be displayed on the radar by_connection an optional add-on terminal board. ‘@ True Motion The JMA.6100 series is provided with a true motion, permitting the operator to monitor the true motions of other ships at a glance as if they were moving on the sea. ©SHM and Bearing Adjustment from Keyboard Installation alignments including antenna bearing and ship's heading marker adjustments are available from the keyboard on the display unit. © Separable Display Unit The display unit can be separated into three sub- units, the display, the operating panel and the processor, ensuring their space-saving installa even on small boats. Options: 1. Performance Monitor (NJU-14) Radar performance degradation can be monitered on the screen as it js needed. External Signal Interface (MDYW03509) The interface allows the system to connect to navi- gation equipment (GPS, NS or Loran navigator), a radar adaptor or a radar buoy. 3.
