The interconnection of dead-reckoning and radar data for precision navigation and prediction

A simplified method for the interconnection of radar and dead-reckoning data has been presented and used to illustrate the application of this principle to ship and aircraft navigation problems. This interconnection facilitates the interpretation of radar data and increases the accuracy of the dead-reckoning data. Furthermore, the prediction of time of arrival of a craft at a stationary or a moving object is readily computed.
