Abstract

PURPOSE:To find a correct target distance for the detectable range of a target in fast movement, etc., by selecting two kinds of pulses among repetitive frequency pulses according to a prescribed detectable range. CONSTITUTION:The size and speed of the target are estimated to make a selection 22 of PRF (pulse repetitive frequency) so that DELTAm>r/ctau (C: light speed, tau: pulse width) for the dispersion distance range (r) (detectable range) of the target, where DELTAm is the difference between the ratios m1 and m2 (m1>m2) of two kinds of PRFs and pulse width. At this time, a decision can be made within a distance range below INT(m2/DELTAm).m1ctau [INT(A): integer part of A]. On the other hand, two out of >=3 kinds of PRFs (R, R', R'') are used selectively so as to cope with the presence of a distance where a sample gate can not be set such as the periphery of a sent pulse position. Therefore, a pulse radar distance decision device 21 of this constitution handles the fast movement of the target in a relatively long processing time to perform a correct decision.
