Indra's frequency modulated continuous wave (FMCW) surface movement radar (SMR) has the advantage of being designed specifically for surface surveillance using the optimal technology for this mission. The benefits of FMCW over other technologies, such as pulsed Doppler (PD), are numerous:1.FMCW radar only needs to transmit low peak power for the same coverage and the lifetime cost is reduced. The use of low radio-frequency power output modules and low-power consumption solid-state devices enable the use of radio-frequency power amplifiers with very high MTBF, which improve reliability and availability since there is no need to adjust magnetrons frequently.2.FMCW radar sees a higher percentage of valid targets due its high resolution.3.FMCW radar does not suffer from the blind distance problem due to the radar transmitting and receiving simultaneously. Therefore, continuous wave radars can receive the signal from the beginning of the transmission, from zero distance.
