A new type of radar waveform called Linear Contracting waveform is presented. To suppress the sidelobe of such waveform's matched output, a digital filter is adopted.

A daily input of water, food, and energy of various kinds is matched by an output of sewage, solid waste, air pollutants, energy, and materials that have been transformed in some way.

These tools typically produce match output that identifies how records are matched or linked and allow insight into variations in domains between matched records.
