Description: BP algorithm was originally derived from McCorkle's computer tomography technology, so-called computer tomography, which is the most common technology in hospitals.
Principle of BP algorithm: BP algorithm refers to the idea of "time delay-overlay". In radar application, it matches the echo signal received by radar receiving antenna in range direction, obtains the phase information contained in the echo data, and then carries out inverse Fourier transform through IFFT, obtains the time delay of the combination of transmitting and receiving antennas, and finally accumulates it. Signal coherence is added to get the objective function.
