This paper presents a comprehensive study on monopulse secondary surveillance radar (MSSR) coverage. The design and radiation pattern of an improved MSSR antenna is presented herein, highlighting the horizontal and vertical factors of the SUM beam. Moreover, the impact of other determinant factors, such as signal reflection and atmospheric refraction, on the radar coverage were assessed in this work. Real positioning measurement data and coverage simulations were used to support and exemplify theoretical findings.

“…It is not recommended to design three different antennas due to the dependency of all three patterns in their processing part and also large amount of required weight and space. On the contrary, it is recommended to generate all three patterns by manipulating the array's excitation coefficients [15] or type of mode excitation [8]. For CTRL pattern only, one good suggestion is the use of a simple monopole antenna or even one of the array elements.…”

“…A well-known more-efficient alternative solution is to design a multi-beam feeding network. This idea, which has been used in radar systems for a long time [15,17,18], paves the way for maximum integration among all three beams, SUM, DIFF, and CTRL, resulting in miniaturization, simplification and reducing the price of the system.…”

In this paper, the design and fabrication of a large array antenna with three required, Sum, Difference and Control beams for a monopulse Secondary Surveillance Radar (SSR) is presented. A special array element, which is a high gain dual dipole structure, is designed and tested. This element has 9.6 dB gain in 1060 MHz and does not need any balun. The main challenge of extracting three beams out of one beam feeding networks (BFN) has been resolved efficiently by maximum integration of all three in one network, reducing the number of required modules to one half. The complete 33-element array, working in 1030 MHz and 1090 MHz is designed based on the Taylor array factor. The complex feed network of this 6-meter long array has successfully been synthesized as modular as possible. Sum pattern was designed for 2.7 o azimuth beam width and -20 dB side lobe level and Diff pattern with a deep null in the boresight of the Sum pattern. The Ctrl beam was also designed in order to cover the Sum beam except in the direction of the main lobe.

“…Since most aircraft are flying at high altitudes, reply transmissions often cover much wider areas than interrogations, leading to an increased frequency occupancy and interference level across large areas. To put this into perspective, surface interrogators usually have a rather narrow beam width of 2-4 degrees [11] whereas replies from aircraft can be received on the ground over distances of more than 400 km in all directions, depending on the aircraft's altitude and the surrounding geography.…”

Receiving signals on the 1090 MHz frequency, one of the most important radio frequencies used in aviation, is typically done using ground-based receivers. However, an increasing number of airborne or even space-based receivers also aim to receive these signals for applications such as air traffic surveillance and collision avoidance. In this paper, we present our results from a high-altitude radio frequency measurement campaign with the goal to gain insights about the challenges and limitations of receiving 1090 MHz signals at high altitudes. We used a high-altitude balloon equipped with a software-defined radio to collect 1090 MHz signal data. In an extensive analysis of these data, we identify several challenges and provide a first impression of the radio environment at altitudes up to 33.5 km.
