AN INTRODUCTION TO PSEUDO-NOISE MODULATION
Abstract
The chief purpose of this report is to provide an introduction to pseudo-noise modulation functions and to describe those properties that make their use in radar systems desirable. Because of the interests of these laboratories, characteristics applicable to fuzes are emphasized. The applicability and usefulness of various pseudo-noise modulation functions in radar systems is discussed. The use of the m-sequence in a complete radar system is described, and an extensive bibliography of other applications to radar systems is also given. A short section containing classified information on jamming of pseudo-noise modulated radars, with bibliography, is issued as a supplement to this report. This report is essentially a survey, and the body of the report therefore contains little new material. However, the three appendices, on mesh relations for sequences with two-level autocorrelation, on the shift-and-add relations, and on filter integration of m-sequences, present material that to the author's knowledge is original.
