The concept of echo-location, that is the transmission of acoustic or electromagnetic energy and the subsequent reception of energy reflected from physical objects or scatterers, is primarily motivated by (1.) the desire to detect their presence, and (2.) to estimate associated parameters such as size, range, speed, and bearing. Secondary objectives which relate to these may involve identification, discrimination, and tracking of specific scattering objects in the presence of competing backscatter sources and noise.
