Now, by creating a mathematical model of interference in FM-CW radars and spread-spectrum radars that simplifies analysis without sacrificing precision, Fujitsu and Fujitsu Laboratories have developed a simulation technology that can analyze interference using a typical PC with ordinary memory and performance levels.
(3) FM-CW radar:A type of radar that emits a frequency-modulated continuous wave and uses the difference between the emitted frequency and the frequency that is reflected back to determine distance and relative speed.
Another disadvantage with a two-antenna, FM-CW radio altimeter system is the need for high isolation between transmitter and receiver antennas, resulting in rigid requirements for antenna side lobe suppression and for the antenna's location on the aircraft fuselage.
