“…It is a set-theoretical methodology for image analysis, can rigorously capture many aspects of the geometrical structure of signals in a way that is consistent with human intuition and perception [9] [10] . Mathematical morphology has been widely used for biomedical and electron microscopy image analysis, and has recently become a topic of interest for academic research in the field of communication signal processing [11] The fundamental operators of mathematical morphology are dilation and erosion, which are defined as in (1) and 2:…”

“…In satellite communication, there are many co-channel interferences that come from the ground wireless communication system, other satellite communication system or some radar signals. How to effectively monitor the co-channel interferences is prerequisite for eliminating it and is basic to improve the system efficiency, so the interference monitor is becoming one of the important issue in satellite communication research filed [1]- [4].…”

How to precisely detect co-channel narrow band interferences using single threshold is a challenge for satellite transponder spectrum monitor, especially in the condition of many signals which parameters are different. A new method for interference detection in satellite communication is proposed based on mathematical morphology. The paper uses an improved morphological gradient filter which belongs to image and graphics filed to deal with the spectrum data that is viewed as one-dimensional gray-scale image, and then search the gradient of interference edges to detect the position of it. Simulation results show that the proposed method can detect interference at one time when there are different signals with interference; it has not effect by the non-flat noise floor and has low computational complexity, is suitable for real spectrum monitor in satellite communication system

“…(4) In station A, if part of the transmission signal is separated and delayed by the time of the satellite round trip, the same signal as S AA can be generated. (5) If the generated S AA of the same amplitude but of opposite phase to the received S AA is added to the received S AA , the received signal S AA can be canceled.…”

“…However, the frequency of satellite communication is open, and the signal‐to‐noise ratio (SNR) of the signal received by the satellite communication earth station is low. For synchronous orbit satellite, the communication distance is more than 36 000 km, and the signal power received by earth station has been very weak (about −115 dBm) 2 . It is vulnerable to the interference, either deliberate or inadvertent.…”

In this study, a novel elliptical widebeam auxiliary antenna is proposed for anti‐interference of satellite communication earth station. The wide beam width of about 180° in horizontal plane (H‐plane) is achieved by increasing the width of the substrate, reducing the size of the ground plane and adding a V‐shaped aluminum frame. And the narrow beam width of about 30° in elevational plane (E‐plane) is achieved by designing a binary element array. Only two auxiliary antennas are needed for sampling to cover interference from any azimuth direction in H‐plane. The antenna is fabricated and measured, and the results are in good agreement with simulation. The corresponding −10 dB impedance bandwidth is about 17% with maximum gain of 6.5 dBi. The 3 dB beam widths are respectively 33° and 178° in E‐plane and H‐plane. Furthermore, simulation and experiment of the proposed auxiliary antenna in interference cancelation system verify its anti‐interference performance. According to sidelobe canceler, an average interference cancelation ratio of about 27 dB is achieved.
