Light-weight radar: its dependence on low-consumption circuits

The paper discusses the design of special radar circuits for use where reduced weight and enhanced reliability are desired. It is concluded that in such instances the circuits form the core around which the rest of the design must be framed. Some of the problems which face the circuit designer are elaborated, the use of pulse ratings, tropic-proofed materials and miniature valves being particularly noted. Circuits are given which illustrate methods of material and dissipative economy. Mention is made of ancillary gear and of the importance attached to careful choice of the source of power, and its precise nature.
