<p>PURPOSE:To remove incorrect bearing calculation without detecting the radar video of a target with its part protruded from a blank as the object of the blank by inputting blank signals to a correlation circuit together with radar video signals and performing the processing of detection inhibition. CONSTITUTION:Videos from a receiver are inputted through an input terminal 1 and the videos above a prescribed level are quantized by a slicer circuit 2 to be inputted to a correlation circuit 5. Blank signals inputted through an input terminal 3 are inputted to the circuit 5 as they are. Since inputted with the whole responses to process them, the circuit 5 can recognize the responses of the radar videos outside a blank region in succession to those in the blank region. Accordingly, a detection inhibition processing is correctly executed and an incorrect bearing calculation is removed.</p> |
