1. The Scatterer of the fear of birth and death.

2. The Mett cross section applies to a point scatterer.

3. Modulated Scatterer Technique (MST) is the key to realize the method .

4. Parameter estimation of radar target scatterer plays an important role in the process of target characteristics analysis and target recognition.

5. Multiresolution analysis is used to estimate the scatterer spacing in biological tissue from the back-scattering signal.

6. In order to reconstruct the shape of scatterer D, we establish the relation between the scatterer and the far field pattern. The relation can be fixed by so called far field operator F.

7. If a scatterer like human head is used , intensity differences among microphones can be obtained efficiently.

8. Mean scatterer spacing( MSS ) is an important parameter for describing the biological tissue microstructure and its ultrasonic scattering characteristics.

9. Average scatterer spacing is one of the important parameters in describing the biological tissue microstructure and its ultrasonic scattering characteristics.
