ABSTRACT:
A radar apparatus having an integral ARPA function transmits at least two kinds of pulse signals, each of which has different pulselength, according to a specific transmission pattern and receives echoes of the transmitted pulse signal. The radar apparatus includes an echo data generator for generating display echo data for each range scale selected for on-screen presentation by using an echo signal obtained with each transmission pulselength, an ARPA processor for generating a single set of motion-related information on each tracked target to be superimposed on the display echo data by using echo signals obtained with the different pulselengths, a display output synthesizer for superimposing the motion-related information on each tracked target generated by the ARPA processor on the display echo data, and a display unit for displaying a superimposed picture produced by the display output synthesizer.
