Title:
PULSE RADAR
Document Type and Number:
Japanese Patent JP3410575
Kind Code:
B
Abstract:
PURPOSE: To provide a pulse radar with which the nearer the distance is, the more the time necessary to detect can be shortened.
CONSTITUTION: A transmitting part of a pulse laser radar is composed of a main oscillator 11, a subsidiary oscillator 12, a mixer 13, an N-divider 14, an M-divider 15, a phase comparator 16, a low band transmissive filter 17, an N-divider 18, a reference time detecting circuit 19, an amplifier 21, and a light emitting circuit 22. Furthermore, a receiving parts composed of a light receiving circuit 31, an amplifier 32, a sample hold circuit 33, a quantizing circuit 34, a memory 35, a memory controlling circuit, a CPU 40, and a reception controlling circuit 50. The reception controlling circuit 50 is composed of N/n dividers 51-56, selectors 57, 58 59, D flip-flop devices 60, 61, and a leading edge detecting circuit 62.
