Introduction of new algorithms in the subsurface detection and review of MAD method

Common methods include the use of sound waves and underwater detection equipment such as sonar (which is divided into two types: active and passive) and Sonobuoy that functions like a sonar is used. In this paper, we introduce new algorithms in this field and the best and most reliable way of Magnetic Anomaly Detection called MAD briefly explain. This detection algorithm, is a method based on the measurement of the smallest changes or disruptions in the Earth's magnetic field by passing a ferromagnetic object and magnetic dipole field generated around it is based. In this paper, the detection of subsurface using the principles and methods of detection of this method are discussed and compared.
