Abstract: the growing demand for security, safety, and environmental protection at the local, state, and federal levels expose the inadequacy of traditional surveillance and control centers to meet the needs and specifications of contemporary border control systems for homeland protection, where both the land border and the maritime border are expected to be monitored. This is true, for instance, of any land border affected by illegal immigration and/or trafficking, as well as any tiny areas, such as vital infrastructure or military or civilian stations in environments with vegetation, such as forests or jungles. Logistics considerations highly advise having very low low-power devices capable of operating for months or years without maintenance in such a demanding environment. Such an instance ought to be ideal for implementing an Unattended For border control, the Ground Sensors (UGS) network uses foliage penetration (FOPEN) radar. This work aims to outline the fundamental properties and initial findings of a surveillance unattended FOPEN (SUF) radar that can identify moving objects, such as humans or cars, in a forested environment. Keywords: Foliage penetration radar (FOPEN), Ground sensor (UGS), Surveillance unattended FOPEN (SUF).
1. INTRODUCTION Radar is an abbreviation for radio detection and ranging. It is mostly used to determine the position, direction, and velocity of an item. Radar is a remote-sensing system that is frequently utilized for both military and civilian surveillance, tracking, and imaging applications [1]. The need for high-powered, economical, and small technology for both military and commercial purposes has led to a renaissance in radar technology. Unmanned aerial vehicles (UAV), and autonomous vehicles, as well as a number of commercial applications, are examples of cutting-edge technology that rely on solid-state radar, whose fabrication and programming have been modified to meet the requirements of the military and civilian markets of the present [2,3]. In this wide spectrum of demands of radar systems, both military and civilian applications, target recognition and identification in the presence of such dense background clutter are important research subjects. For instance, in contemporary conflict, enemy military targets like tanks, artillery, and other weapon stockpiles can find protection in the forest.
2. BACKGROUND Early in the 1990s, there is a significant upsurge in the development of foliage penetration radar for military, geoscience, and civilian uses. Starting in 1990[4], as a risk reduction for the development of a more reliable foliage synthetic aperture radar (SAR) system. In the following years, research was started at a number of government institutions, including the NASA jet Propulsion Laboratory, Sweden's Defense Research Establishment, the US Army Research Laboratory, the US Air Force Research Laboratory[5], and the US Naval Air Development Center. The low very high frequency (VHF) band (30 MHz) through the C-band was used for the foliage radar data collection (6 GHz). Instrumentation systems, including
