Frequency Modulated Continuous Wave Radar (FM CW Radar)

Technology / Radar / Frequency Modulated Continuous Wave Radar (FM CW Radar): Frequency modulated continuous wave radar makes use of frequency modulation to allow the range of a target to be measured. MORE

Wave Frequency

Technology / Radar / Wave Frequency: The number of cycle of waves that passes a point in one second. Frequency is measure in hertz (hz). Wave frequency is inversely proportional to wavelength. MORE

Cutoff Frequency Filters

Technology / Home Audio / Cutoff Frequency Filters: The frequency at which a signal falls off by 3 db (the half power point) from it's maximum value. Also referred to as the -3 db points, or the corner frequencies MORE

Digital Radio Frequency Memory (DRFM)

Technology / Radar / Digital Radio Frequency Memory (DRFM): Digital radio frequency memory is an approach being adopted by modern electronic attack (ea) systems to combat pulse-compression radar. A digital radio frequency memory system receives radar pulses, s MORE

Frequency Diversity

Technology / Radar / Frequency Diversity: Frequency diversity refers to the use of complementary radar transmissions or multiple radar systems operating cooperatively at different frequencies. MORE

Automatic Frequency Control (AFC)

Technology / Radar / Automatic Frequency Control (AFC): An electronic means for preventing drift in radio frequency or maintaining the frequency within specified limits. The afc maintains the local oscillator of the radar on the frequency necessary to obta MORE
