Abstract

The article discusses ways to improve the detection efficiency of small and low-speed objects in conditions of intense background reflections. The properties of the ultrashort pulse echo signals are investigated. The phenomenon of interfering visibility is investigated.

Highlights

The problem of ensuring the security of crowded places, territories of various facilities, such as airports, directly related to round-the-clock and all-weather monitoring of low-speed small-sized objects on the background of the earth's surface, is very relevant
One of the most difficult objects from the point of view of detection for radars providing monitoring of the entrusted territory is small unmanned aerial vehicles (UAVs) that have the following features: the ability to move at low altitudes at a wide speed range: from fractions to 70-80 meters per second, including the possibility of hanging in place, and small RCS [5]
Due to the small RCS, such objects are extremely difficult to detect in the presence of passive interference from the earth's surface and local objects using traditional radars

Introduction

The problem of ensuring the security of crowded places, territories of various facilities, such as airports, directly related to round-the-clock and all-weather monitoring of low-speed small-sized objects on the background of the earth's surface, is very relevant. One of the most difficult objects from the point of view of detection for radars providing monitoring of the entrusted territory is small UAVs that have the following features: the ability to move at low altitudes at a wide speed range: from fractions to 70-80 meters per second, including the possibility of hanging in place, and small RCS [5]. The problem of detecting small-sized low-speed targets in conditions of intense interfering reflections from the underlying surface and local objects with using radars is extremely important
