After finishing up one more detection-range example (that didn't fit into last month's column), we'll cover the general purpose of radar modulation and the types of modulations. Then (over the next couple of columns) we'll focus on the characteristics and applications of the common radar modulations.
Detection Range for ELINT Receiver
An ELINT receiver will typically not be located in the main beam of the radar antenna. Thus, the transmitter-antenna gain is that of the radar-antenna sidelobes. It is common practice to assume that the sidelobes of a narrowbeam antenna are 0 dBi. This means the sidelobes are lower gain than the main beam by an amount equal ...
