Does anyone know what non-traditional radar could mean?

  It's "non-traditional radar waveform". They are referring to waveforms and modulation techniques not traditionally applied to radar signals. Radar typically has a very regular waveform. So regular, in fact, that a receiver can tell what type of radar is sending the signal by recording the overall signal pattern and deriving radar parameters from that (center frequencies, chirp bandwidths, scan patterns, and such). The type of obfuscation they are doing here is more typical of communications systems.

  It looks like it combines features from pulse-Doppler radar and noise radar. It amplitude and phase modulates a complex pulse-linear FM waveform (linear chirp) using pseudo-noise. I'm not familiar with this particular research. ACPN is not something US army just discovered. Agile beam, agile frequency, pulse compression and pseudo-noise waveforms are the direction military radars are going towards.

  At a guess, it includes things like the tricks in http://dtic.mil/dtic/tr/fulltext/u2/a456960.pdf http://dtic.mil/dtic/tr/fulltext/u2/a456960.pdf ("DETECTION AND JAMMING LOW PROBABILITY OF INTERCEPT (LPI) RADARS") but (1) it's obviously not a very precise term and (2) it would be surprising if all of the relevant techniques were available in an unclassified review from 2006.
