In contemporary society, the usage of electronic explosive devices in acts of terrorism presents a significant peril to the well-being and employment of the civilian populace. Electronic explosive devices are improvised constructions made from readily accessible materials and explosives, which may be remotely ignited using radio equipment and cellphones. This technology enables terrorists to selectively target civilian objects and vital infrastructure, resulting in widespread fear, devastation, and loss of human life. Some instances of such attacks include detonations at transportation hubs, retail complexes, and athletic competitions. To address this danger, a comprehensive set of actions is necessary, such as enhancing technologies for identifying and rendering electronic explosive devices ineffective, enforcing stricter laws and broa­dening police operations, and bolstering global collaboration in the realm of counterterrorism. Nevertheless, the ongoing advancement of electronic technology and the emergence of new terrorist strategies underscore the importance of enhancing technologies to combat terrorist activities. A current urgent objective is to ascertain the angular coordinates of electronic explosive devices, which are objects with low contrast and non-linear search characteristics, in the presence of radio signal reflections off the Earth's surface. An approach used to ascertain the coordinates of objects is the radio direction finding method. An important aim of this work is to analyze and contrast radio direction fin­ding techniques for detecting the angular location of a nonlinear search object. This will be achieved by utilizing a nonlinear reconnaissance radar station that is mounted in a secure vehicle.
