Designing of an Adaptive Adcock Array and Reducing the Effects of Other Transmitters, Unwanted Reflections and Noise

In the design of modern high frequency radio direction finder (DF), multi elements DF antennas are used. The advantage of DF to the conventional types is in utilizing four elements. Error of arriving wave angle and calculated angle depends on few factors, such as array dimensions, number of elements, and location of main transmitter. Recently research works have been reported on reducing error between arriving wave angle and calculated angle but in practical case, other transmitters, unwanted reflection and the noise could increase the error. In this paper, we investigate effect of above parameters on the error then by using adaptive blind algorithm, these effects are reduced and SINR in output is increased
