Orthogonal‐polarization alternating codes

Abstract

We propose that by using orthogonal polarizations for alternating bauds of an alternating code, improvements are available both in cycle length, by means of using weak condition alternating codes, and in code performance through a reduction of autocorrelation function estimate variances by a factor of 4. This means an increase in the speed of incoherent scatter radar experiments by the same factor of 4.
