The range resolution is normally some fraction bandwidth of the pulse. The fraction will depend on how you measure it i.e. null to null, 3dB points, 6 dB points etc. Also the windowing (Hamming, Kaiser) used will reduce the resolution i.e. increase the number. For a chirp pulse with the bandwidth you stated the null to null width is given by. how often do worms lay eggsWebThe higher the angular resolution and the larger the FOV, the greater the number of channels are required. For instance, to achieve 3 resolution within an FOV of 60 requires approximately 40 channels for a 77GHz radar. It is even harder to have both high angular resolution in azimuth and elevation while covering a large FOV. In that case, how often do women shave their legsWebmultiple receive antennas.
