Wideband radar (advantages and problems)

Review of advantages and problems of wideband radar is given. Some criteria of wideband (UWB) radar are discussed to avoid misunderstanding when only the relative signal bandwidth is used as a criterion. Brief historical outline of the first and follow up experiments by different authors is presented. Advantages and disadvantages of bandwidth widening can be compared using the computer simulation of scattering. Experience of various simulation methods use, their applications to the target detection, tracking and recognition problems are briefly discussed and compared with experiment. Interference immunity, electromagnetic compatibility, stealth of radiation (low probability of intercept- LPI) for radar, and the possibility of creation of antiLPI passive radar are also discussed.
