We present a new class of alternating codes. Instead of the customary binary phase codes, the new codes utilize either p or pĝ€"1 phases, where p is a prime number. The first class of codes has code length p m, where m is a positive integer, the second class has code length pĝ€"1. We give an actual construction algorithm, and explain the principles behind it. We handle a few specific examples in detail. The new codes offer an enlarged collection of code lengths for radar experiments.
