Abstract

The well-known radar equation for sinusoidal waves is extended to apply to nonsinusoidal waves, in particular to binary waves with the two values ±E and ±H for the electric- and magnetic-field strength during signal transmission. Three major modifications have to be made: the concept of radar cross section is changed; the gain of the radiating antenna and the resolution angle of the receiving antenna are different from the values holding for sinusoidal waves; and the effect of noise is modified, primarily due to the absence of a rectifier
