战术导弹用的小型雷达给微波工程师们提出了有意义的课题。如果考虑的是空中目标——与舰船目标相比——这些课题是特别困难的,如果包括地面目标,则这些课题甚至更为艰巨。军舰,由于其横截面大,且海杂波比较好对付,故已成为主动雷达导引头的首要目标之一。这种主动雷达导引头的设计较为简单,可采用非相干脉冲波形,非常类似于早期的载机雷达。 Small radars used in tactical missiles have given microwave engineers significant questions. These topics are particularly difficult if airborne targets are to be considered - as opposed to naval targets - and they are even more arduous if ground targets are included. Warships, due to their large cross-section and good sea clutter, have become one of the primary goals of active radar seekers. The design of such an active radar seeker is relatively simple and can employ incoherent pulse waveforms that closely resemble those of earlier carrier-based radars.
