【Abstract】 The automatically scaling system on laser speckle radar is part of key laboratory fund item from chief arming ministry - the study of missile target laser scattering characteristics. It is intended to provide technical basis for stealth and antistealth technology, the extraction of target characteristics and the recognition of target, infrared guiding technology , etc. The work is of great importance to the modernization of national defense and the development of national economy.This paper mainly introduces the established process of the automatically measuring system on laser scattering, and mends the design of the system’s software, and some samples are measured and analyzed in theory. We adopts the up to date scaling technology , elementarily develops the automatically scaling system on laser speckle radar as a reference to the former work in scaling laser scattering. Some samples are measured and analyzed in theory. This paper mostly includes the following aspects:1. Based on the theoretical study of rough surface scattering, The experiment system is demonstrated to be feasible.2. As a reference to the overseas up-to-the -minute academic model on scaling laser scattering, we make use of the technology of the homodyne interferometer detection and design the light route framework of the experiment system.3. Combined with the existing experiment condition ,we design and install the machinery of the system., design the circuit and PCB diagram of the controlling card , make out the circuit board to debug and pass .4. The software is designed and exploited to drive motors and collect data, and a testingsoftware is exploited to check up the capability and precision of the system.5. We debugged the experiment system, and test its capability, and put forward to the element scheme on data. processing. Some samples are scaled and comparatively analyzed.更多还原
