Radio direction finders have long been widely used in both civilian and military applications to locate sources of radio emission. However, there is still a need to improve both the methods of direction finding and the on-board direction finders that use these methods. There are many challenges associated with increasing the accuracy and likelihood of detecting radio emission sources. This article provides an overview of direction finding methods on-board. It discusses existing direction finders, their advantages, and disadvantages. To analyze the existing types of radio direction finders in terms of their operating methods and the antenna systems used in them. The analysis of the existing methods of direction finding and radio direction finders operating on the basis of these methods is carried out, the advantages and disadvantages of each direction finding method are presented.

The article shows the existing types of radio direction finders in terms of their operating methods, lists the advantages and disadvantages of direction finding methods, and provides links to manufactured radio direction finders. This information can be used by developers when designing a radio beacon-radio direction finder communication channel, as well as by companies that need to use an already manufactured radio direction finder to solve their problems.
