My reading, based mainly on what they called it (Advanced Pulse Compression Noise), is no. I think what they are doing is adding an extra step that convolves the transmitted signal with a random noise signal before transmission, then deconvolves it when received as part of the normal convolution step in pulse compression.

They may also be randomly shifting the center frequency and chirp bandwidth in top of this. Frequency-hopping radar is not a new idea.
