The backward propagation technique is known as one of the most widely used algorithms in acoustic imaging for its simplicity, stability, and resolving capability. This presentation provides an overview of the development of backward propagation based algorithms for various system configurations in a systematic manner, from the simple case of coherent systems with stationary sources to the more complex wideband pulse-echo systems for time-varying objects, in both monostatic and bistatic modes. With this treatment, it is now possible to establish an accurate assessment of systems' performance in terms of computation complexity, algorithm structure, sensitivity, and limitations.
