Impact of Internal and External Interferences on the Performance of a FMCW Radar
1 Telecommunication Research Institute Ltd., Gdansk, Poland
ABSTRACT: Although FMCW technology has become by now mature, there are still some unsolved problems left. First group of them are noise and distortion from own transmitter or receiver. They are usually caused by DDS (Direct Digital Synthesis) and power converters performance. They appear on radar display as circles or arcs because of their isotropic properties. Second group are interferences from external world like beams of pulsed radars working in the same frequency band, reflections from close buildings and installations or sea clutter. Apart from creating artificial echoes of target they can cause degradation of radar tracking system. This paper evaluates influence of internal and external sources of interferences on the FMCW radar performance. DSP (Digital Signal Processing) algorithms which optimize detection of FMCW radar were presented. Means of suppressing analog interferences by digital techniques were shown as well.
