Sonar (Sound Navigation and Ranging) system is an advanced underwater object-detecting system for navigation. The sonar system aids in detecting obstacles and the presence of enemies within a given range. The sonar system detects the targeted objects by identifying the radius and range of the targeted objects. One of the major problems that affect the application of the sonar system is the inability to detect objects due to excessive echoes and noise in the spectrum. The excessive echoes created reverberations that tend to distort the original reflected signal of the sonar system. This research aims to develop a sonar system that can detect a target object at 15km using a beamforming technique. The technique aids in creating a very high-level concentration on the objects by sending multiples of the same signals to one receiver, thereby reducing reverberation and transmission losses. The results show that 15 obstacles were detected at 15km, and reverberations were reduced by 2dB, thereby improving the visibility of the detected signal within its range with the lowest transmission loss of 0.5dB compared to the ultrasonic sonar system and the conventional echo object detecting system having a transmission loss of 3.12dB and 5.67dB respectively.Keywords

Parabolic antennas are used in a variety of communication systems including satellite communication. Signal loss due to distance and misalignment is a significant problem facing the satellite industry today. The research work is aimed at improving the parabolic reflector antenna in terms of gain and signal quality and is undertaken using CST simulation. This consists of employing the use of double sub reflectors on the main parabolic reflectors, which keeps the EM wave within the enclosure of the feed antenna and the main reflector. This will then aid the antenna to accumulate more signals as well improve the gain of the antenna. The results of this research show that the antenna performance has a radiation efficiency of 85% at an antenna power of 0.5 watts, with a VSWR of less than 2 and a maximum radiation directivity of 8.94 dB. The double sub-reflector gain is found to be 40 dB. In conclusion, the research work considered the diameter of the parabolic reflector, the focal length, the diameter and lend length of the sub reflectors and the width and length of the feed horn antenna. For further research, it is recommended that other advanced techniques be used for the improvement of the gain of the parabolic antenna.Keywords
