ABSTRACT:
A radar apparatus displays echo signals in a manner that desired echo signals can be easily distinguished from unwanted echo signals such as sea clutter and the like and eliminated, when any one of display modes is selected. The radar apparatus includes a receiving unit for receiving echo signals, a buffer memory for storing echo signals resulting from one search signal and produced by the receiving unit, a first memory for storing echo signals coming from a wide range of directions in memory elements corresponding to points on the surface of the search at which the echo signals are generated respectively, signal process device for applying a signal process on the signals outputted from the buffer memory and the signals read out from the first memory and supplying resultant output signals to the first memory, a second memory for storing the output signals of the correlation means in corresponding memory elements thereof determined in compliance with a display mode selected, and an indicator for displaying the signals read out from the second memory.
