Radio frequency interference (RFI) is a major issue in accurate remote sensing by a synthetic aperture radar (SAR) system, which poses a great hindrance to raw data collection, image formation, and subsequent interpretation process. This paper provides a comprehensive study of the RFI mitigation techniques applicable for an SAR system. From the view of spectrum allocation, possible terrestrial and spaceborne RFI sources to SAR system and their geometry are analyzed. Typical signal models for various RFI types are provided, together with many illustrative examples from real measured data. Then, advanced signal processing techniques for removing RFI are reviewed. Advantages and drawbacks of each approach are discussed in terms of their applicability. Discussion on the future trends are provided from the perspective of cognitive, integrated, and adaptive. This review serves as a reference for future work on the implementation of the most suitable RFI mitigation scheme for an air-borne or space-borne SAR system.

“…According to Ref. , 28 GHz band is proposed for Earth Stations in Motion (ESIM) remote sensing and International Mobile Telecommunications (IMT) standards which are relevant to microwave remote sensing. Our proposed antenna covers this band and can be used as an image sensor in IMT standards and ESIM remote sensing applications.…”

In this article, a novel, simple, and compact structure of dielectric resonator antenna is proposed, which provides wide bandwidth across proposed mm wave band for microwave image sensing with considerable gain using a lossy FR‐4 epoxy substrate and thick FR4 as DRA. A DR can be excited using four‐line feed using a circular loop type feed network. These line feeds maintain phase difference of 90° to produce CP. This antenna provides approximate constant gain of 8.6 dB on 25‐26 GHz band and 3 dB axial ratio bandwidth is almost 1 GHz from 25.2 to 26.2 GHz, Impedance bandwidth of the proposed antenna is 3 GHz (24‐27 GHz). This antenna can be used in microwave image sensing and wearable sensors applications, due to its compactness (30 × 30 mm2), in mm wave band.

“…A First Conference Preparatory Meeting (CPM-1) is held to coordinate the work on the agenda items among six Study Groups of the ITU-R, which carry out technical studies with the contribution of the ITU Member States and Sector Members. Approximately six months before the WRC, a Second Conference Preparatory Meeting (CPM-2) takes place to consolidate the technical input for all study groups into one CPM Report that will then be used as a guideline in making decisions at the WRC [3].…”
