Revisions of convolution model of reflected seismic wave

The convolution model of reflected wave used in exploration physics has no serious physical concept and mathematical proof. Wave phenomena should be c haracterized by instantaneous spectrum in physics and a complex function of three real variables (time, place, frequency) in mathematics. Reflection c oefficient is also a complex function of place and frequency. Several new f ormulas instead of convolution model are given. Based on wavelet transform and a method of "3 basis colors", new color sectional image is obtained fi om practical data.
