Claim 10:
11. The method according to claim 1, wherein
said at least one HF transmit beam is scanned through a region of the object as one of i) across a 2D surface region, and ii) across a 3D region, and
receiving for selected HF transmit beams within said region, HF cross-beam receive signals scattered from the HF transmitted pulse for at least two HF receive cross-beams with close distance along each selected HF transmit beam, and
processing said HF receive signals to form one of both of 2D and 3D images at image points within said 2D and 3D region of at least one of
i) an estimate of the NPD, and ii) an estimate of a nonlinear propagation parameter, and iii) a quantitative estimate of a nonlinear propagation parameter βp(r), and iv) an estimate of the linearly scattered signal, and v) an estimate of the nonlinearly scattered signal, at image points.
