Sidelobe blanking system. This legacy motivates the core of the present paper which addresses the design of SideLobe Blanking (SLB) architectures capable of providing Electronic Protection (EP) against a coherent repeater interference in the presence of continuous jamming signals. Here, the authors study the optimum Neyman–Pearson type sidelobe blanking (SLB) detectors for the Swerling target models to assist the design of Maisel blankers. Jan 1, 2026 · To improve the imaging quality and reduce the hardware complexity of the ultrasound imaging system with piezoelectric transducers, this paper proposes an improved sidelobe blanking beamforming method (ISLB) in the field of non-destructive testing. To mitigate the effects of sidelobe signals, a sidelobe blanking (SLB) architecture is proposed by Maisel in [1]. In the Maisel structure, two receiving channels are used. Dec 31, 2014 · A sidelobe blanking system can be looked upon as a method for maximizing main-lobe-detection and minimizing sidelobe detection. The SLB characterizer component is positioned between a radar data processor and beam steering generator of a radar system. May 1, 2011 · The conventional sidelobe blanking system, known as the Maisel sidelobe blanker, uses two receiving channels with different gains to detect the presence of a jammer. A comparator is used for blanking the video output Apr 15, 2011 · Sidelobe blanking (SLB) is used in radar systems to mitigate impulsive interference that enters the radar through a sidelobe of the primary antenna. A second, auxiliary antenna and channel are employed by an SLB system to produce a second output. Abstract This study proposes a sidelobe blanking (SLB) system with a spatial delay line canceler (DLC) and non-coherent integrator in a uniform linear array. The first one is the main channel whose Sidelobe suppression is an important criterion for interference immunity in military radar equipment. However, the radar is not able to distinguish between the main lobe and the sidelobes from the signals of only one antenna and one receiver channel. The Maisel system is an ad-hoc The paper starts with a brief retrace of some seminal publications of Dr. The paper discusses the basic principles and effectiveness of a sidelobe blanking technique devised to reduce any low duty cycle signal coming through the sidelobes of the radar antenna. The sidelobe receiver system in accordance with the invention also includes an arrangement for selecting the above described sampling prior to threshold operation when the input signal is limited and for selecting operation with normal sidelobe blanking comparison of compressed sidelobe signals when the input signal is at a level lower than the Antennas for search radars which continuously scan through 360 deg in azimuth are usually characterized by a high-gain main lobe and many minor lobes. Yet, it has been successfully utilised in numerous operational systems. The system is intended to provide only main-beam signals and thereby producing unambiguous bearing information. Gerlach on adaptive antennas. The Maisel system is an ad-hoc de A sidelobe blanking system is provided which uses as much of the existing radar tracking system as possible while requiring a minimal number of additional components. R. . ∗ Department of Space, Earth and Environment Division of Microwave and Optical Remote Sensing A sidelobe blanking system can be looked upon as a method for maximizing main-lobe-detection and minimizing sidelobe detection. The analysis of a common two-channel system is presented in which the relationship between the probability of main-lobe detection and the probability of sidelobe detection are given in terms of false-alarm probability Dec 31, 2014 · A sidelobe blanking system can be looked upon as a method for maximizing main-lobe-detection and minimizing sidelobe detection. K. This latter output is compared to that of the primary antenna channel, and a decision is then made, based on the classic Maisel SLB architecture, as Dec 1, 2016 · The conventional sidelobe blanking system, known as the Maisel sidelobe blanker, uses two receiving channels with different gains to detect the presence of a jammer. The Maisel system is an ad-hoc detector without any optimality properties. Sidelobe blanking systems are useful in preventing acquisition of strong targets in the antenna sidelobes and also in rejecting pulsed interference originating in the sidelobes. In the conventional radar systems, the interfering signals intercepted from the antenna sidelobes can cause problems such as false target detection and poor tracking accuracy etc. The method and system of the present invention includes a SLB characterizer component for achieving optimum sidelobe blanking through the combining of multiple dimension data into a single figure of merit comparison. After the equations for the target and noise power in the SLB system were established, SLB-ratio functions for the proposed and conventional SLB channels were developed. The system is intended to Sidelobe blanking characterizer system and method Abstract According to a particular embodiment, a method for evaluating different antenna designs includes receiving different sets of antenna patterns representative of the different antenna designs from a corresponding number of data sources. In this respect, a generalized Jul 25, 2017 · The sidelobe-blanking (SLB) device, used in connection with the radar system, reduces the number of false alarms when the interference impinges on the antenna sidelobes. The sidelobe blanking system includes a guard antenna and two phase shifters the first of which is operably coupled to the main radar antenna's sum pattern. Apr 15, 2016 · The conventional sidelobe blanking system, known as the Maisel sidelobe blanker, uses two receiving channels with different gains to detect the presence of a jammer. vee clp wao fty xyu gvy ttk skg kno pqo xpq gxf qno dxi jnc
