论宽带相控阵雷达的战术优越性＊

本文指出由于超大规模集成电路的飞速发展和价格不断下降,成本不再是制约因素,相控阵雷达特别是固态相控阵在90年代将由于性能价格比的不断上升而被愈来愈多地采用。宽带相控雷达有其独特的应用价值。文中将全阵面波束电扫只需用移相器称为准宽带,指出准宽带由于实现容易将是90年代最有实用价值的一种带宽形式。将整个天线必须分成若干子阵,子阵间用实时延迟线称为宽带,认为只有少数特定要求才不得不用宽带。

Tactical Advantages of Quasi-Wide-Band Phase Array Radar

Due to the racing development of the Very Large Size Integrated Circuit (VLSIC) and its decreasing price annually, the cost of phase array radar is no longer a deadly obstacle for the designer or user. It can be sure that phase array radar and especially the solid state ones would be very cost effective in the complex situation in the 1090's, and wide band phase array radar has advantages in its performance and suitable for many specific uses. In this paper, we separate the wide band into two categories: those need only use phase shifter as quasi-wide-band and those need use both phase shifter and real-time-delay-line as wide-band. We pointed out that quasi-wide-band has many advantages and therefore could be most properous radar system in the coming decade, and wide-band phase system would be only used in some limited special situations.
