WebNov 30, 2024 · Consider the case where we want to take a typical FMCW automotive radar and double its resolution. We could do this by simply doubling the number of antenna elements. However, we could get the same result by just adding 1 more Tx antenna. It is this multiplexing between multiple antennas that increases resolution on the Rx side and the … WebAug 18, 2015 · 2. 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.
