The influence of VLSI and VHSIC on radar architecture
Abstract
A synopsis is provided of very high speed integrated circuits (VHSIC). The U.S. VHSIC program was formally conceived in mid-1978 and is generally directed toward achieving 50 to 100 times faster signal processing speeds than do commercial ICs while simultaneously achieving a 10 fold reduction in size, weight, and power consumption. Developments related to monolithic microwave integrated circuits (MMIC) are examined. It is pointed out that the first X-band MMIC was demonstrated by Mills et al. (1977). The extremely small size and cost of the technology enables the radar engineer to consider the use of dual simultaneous carrier frequencies to overcome such problems as multipath and scintillation without resorting to more exotic modulation techniques. Attention is also given to the digitization of microwave signals and gigabit logic devices. It is concluded that electromagnetic systems designers have now at their disposal selected monolithic circuits replicating conventional circuit functions.
