Abstract

Radar and sonar systems are crucial for various applications, including surveillance, navigation, and environmental monitoring. However, traditional methods often struggle with noise interference, bandwidth limitations, and computational inefficiencies, leading to reduced detection accuracy and slower processing times. To address these challenges, a novel method is proposed that leverages advanced electron devices optimized for high-frequency operations and a hybrid simulation approach, enhancing the performance of radar and sonar systems. The proposed method was evaluated across two frequency ranges: 1 GHz to 10 GHz for radar and 1 kHz to 100 kHz for sonar. The results demonstrated substantial improvements in key performance metrics. The Signal-to-Noise Ratio (SNR) achieved 16.8 dB for radar and 25.6 dB for sonar, surpassing existing methods such as HFSS and CST Microwave Studio, which recorded SNRs of 14.2 dB and 21.0 dB, respectively. Bandwidth Utilization (BU) also improved significantly, reaching 85% for radar and 80% for sonar, compared to the maximum of 72% for HFSS. Detection Accuracy (DA) increased to 90% for radar and 88% for sonar, while Computational Efficiency (CE) rose to 200 iterations per second for radar and 180 iterations per second for sonar, outperforming all existing methods in both frequency ranges. These results underscore the proposed method’s effectiveness in enhancing radar and sonar system performance, providing clearer signals, higher detection rates, and faster processing times. The advancements presented herein not only address existing limitations but also offer a pathway for future innovations in radar and sonar technology.
