interrupted continuous wave การใช้

• Strictly, on-off keying of a carrier should be known as " Interrupted Continuous Wave " or ICW or on-off keying ( OOK ).
• In November 2003, approximately from the Azores, the Royal Netherlands Navy ( RNLN ) frigate APAR radar ) guiding a missile using the Interrupted Continuous Wave Illumination ( ICWI ) technique in an operational environment.
• Previously only spark, ICW ( Interrupted Continuous Wave ) signals which were produced by a motor chopping or turning the signal quickly on and off at an audio rate, or modulated continuous wave ( MCW ), could be decoded.
• Because the DBR provides Interrupted Continuous Wave Illumination instead of the Continuous-wave radar used on the other DDGs, the Zumwalt class requires modified versions of the ESSM and the SM-IIIA missiles and cannot use the other kinds of Aegis missiles.
• These firings were particularly significant in that they were the first ever live firings involving a full-size ship-borne Active Electronically Scanned Array ( i . e ., APAR ) guiding missiles using the Interrupted Continuous Wave Illumination ( ICWI ) technique in an operational environment.
• The primary sensors for this role are the long range surveillance radar SMART-L and the multi-function radar APAR is an X band radar providing precise target tracking, a highly capable horizon search capability, and missile guidance using the Interrupted Continuous Wave Illumination ( ICWI ) technique, thus allowing guidance of 32 semi-active radar homing missiles in flight simultaneously, including 16 in the terminal guidance phase.
