Abstract

PURPOSE:To extend a maximum detection distance while holding a maximum speed constant by alternating two kinds of pulse repetitive frequencies at intervals of a constant horizontal angle scan, and comparing and processing results obtained by taking an observation by using pulses of said frequencies. CONSTITUTION:The horizontal scan is made by alternating the two kinds of trigger signals at constant angle intervals and the mean speed is found individually in the section 16a of the trigger signal t1 and the section of the trigger signal t2, i.e. a section 16b whose PRF is a half the PRF of the section 16a. Here, when the transmission output is sufficiently high, it is considered that the observation result of the output mean speed 17 (conventional example) contains a response to a last sent pulse as well as a normal response, so the mean speed is compared with an output mean speed 18 to obtain a mean speed 19 after extension.
