战术导弹的小型雷达向微波工程师们提出了重大挑战。与海上目标相比来考虑空中目标,这些挑战是特别严酷的,而如果必须把地面目标包括在内,则这些挑战可能更加严峻。由于雷达截面较大,海面杂波较弱,军舰就是主动雷达导引头的首要目标。这种反舰的主动雷达导引头的设计是简单的,采用通常的固定脉冲波形,与早期机载雷达非常相似。 Small radars for tactical missiles pose significant challenges to microwave engineers. These challenges are particularly harsh considering air targets compared to those at sea, and those may be even more severe if the ground targets must be included. Due to the larger radar cross section and the weaker clutter on the sea surface, the warship is the primary target of active radar seeker. The design of this anti-ship active radar seeker is simple and uses the usual fixed pulse shape, much like the early airborne radar.
