“…In the data signals, navigation messages and pseudo-codes are modulated, and the signal power is estimated to be 25% of the total power. In the pilot signals, overlay codes and main codes are modulated, and the signal power is estimated to be 75% of the total power [5]. Due to the greater share of the pilot signals in terms of signal power, a significant increase in the code error rate of the received data signals is observed.…”

The GPS system is a navigation satellite system with high precision, all-weather service, and global coverage, whose main purpose is to provide real-time and continuous global navigation services for the US military, and whose signal interference in wartime is a heavy blow to the US military. Its existing interference measures are classified into two types: blanket jamming and deception jamming, with the latter having better interference effects due to its imperceptibility. Frame synchronization, as the foundation of deception jamming, is a focus of current research on navigation countermeasures. This paper discusses the frame synchronization of CNAV-2 messages in GPS L1C signals and proposes a frame synchronization algorithm based on association rules. It analyzes the structural characteristics of CNAV-1 message data, reveals the hidden mapping relationships in the BCH code sequence of the first sub-frame by applying association rules, and achieves a blind synchronization of navigation messages by counting the types of mapping relationships and calculating the confidence levels. The simulation test results show that the proposed algorithm displays high error resilience and correct recognition rates and demonstrates certain values in engineering applications.

Composite structure with embedded microstrip antenna array is a multifunctional structure that can provide the capabilities of a panel skin structure and a radar antenna simultaneously, and it is usually installed in the structural surface of the air, water, and ground vehicles. The environmental load under in-service conditions leads to structural deformations of the composite antenna structure. In this paper, theoretical analysis and experimental validations were presented to investigate the deformations of the functional surface in the composite antenna structure. An electromechanical coupling analysis method was proposed to evaluate the performance of the deformed composite antenna structure subjected to external loads. Composite antenna structure specimens were designed, fabricated, and measured. Using the specimens, experimental systems were built to investigate the deformation. The results show that structural deformation decreases the electromagnetic performance of the composite antenna. The coupling analysis method can be applied to evaluate the performance of the deformed composite antenna structure at the design stage.

An active skin antenna is a multifunctional composite structure that can provide load-bearing structure and steerable beam pointing functions, and is usually installed in the structural surface of aircraft, warships, and armored vehicles. This paper presents an innovative design of the active skin antenna, which consists of a package layer, control and signal processing layer, and RF (radio frequency) layer. The RF layer is fabricated by low temperature co-fired ceramics, with 64 microstrip antenna elements, tile transmitting and receiving modules, microchannel heat sinks, and feeding networks integrated into a functional block 2.8 mm thick. In this paper, a full-sized prototype of an active skin antenna was designed, fabricated, and tested. Moreover, a coupling analysis method was presented to evaluate the mechanical and electromagnetic performance of the active skin antenna subjected to aerodynamic loads. A deformed experimental system was built to validate the effectiveness of the coupling analysis method, which was also implemented to evaluate the performance of the active skin antenna when subjected to aerodynamic pressure. The fabricated specimen demonstrated structural configuration feasibility, and superior environmental load resistance.
