RADAR SEAFALCON/N
Automatic STCNon-Isotropic Clutter Distributiondue to strong wind in coastal area
CFARThree small fishing boatsmasked by dense rain clutter
Scan to Scan CorrelationSmall RIB approaching in Sea State Level 4 at about 1,5 NM
Processing and presentation:• ease of usage through a user-friendly interface with keyboard and graphic presentation based on pop-up/pull-down menus allowing to open/close windows for data and functions management through a trackball-controlled cursor
• range scales: from 0.0625 to 96 n.m. (130 n.m. with off-center)• two VRM, two EBL and an electronic marker with off-centre capability• echo stretch, allowing the enhancement of small radar returns• plot function of all echoes preceding positions with automatic decay, user programmable• PPI off-centre: off-centre representation of radar image in all directions• signal processing functions: FTC, STC, interference rejection, CFAR, pulse-to-pulse correlation, scan-to-scan correlation, echo stretcher
Display type:• colour 23” flat screen monitor• very wide selection of radar controls (e.g. range scale, PRF, PW, interference rejection), video controls (STC, FTC, gain) and tools (EBL, VRM...)
System interfaces:• all the on-board navigation sensors, such as GPS, compass or gyrocompass, LOG, plotter, etc.• other devices, such as AIS, TLC, etc.• high-speed Ethernet connection for data sharing
System management and maintenence:• ease of fault detection, due to comprehensive BITE system• ease of access for maintenance, due to easy access to all replaceable parts
