Research Of Hand-held Through The Wall Radar System

For through-wall radar in the military, security and other fields has become an increasingly widespread use of domestic currently developed through the wall radar has a larger volume and weight, non-portable, and higher research and development costs, inadequate performance and other shortcomings, this paper these shortcomings have been miniaturized radar system research, design and implementation of two handheld wall radar products, which are hand-held pitch-catch through wall radar systems and handheld out of two received through wall radar systems to meet different needs of users for radar detection. Handheld pitch-catch through wall radar system has a small, light, portable and other characteristics, mainly used to meet the requirements of users of portable high-low two-dimensional position, used for the needs of the estimated number of aspects. Handheld radar system out of two received in the volume, quality and portability and did a certain amount of compromise, but still has a small, light, portable features, mainly used to meet user needs the higher requirements in targeting. The main contents are as follows:1. Miniaturized analysis and key technical analysis: the complete radar system miniaturization some analysis to determine the different needs on the hardware, including the key technology, followed by the relevant indicators of radar detection algorithm for analysis.2. Hand-held radar system design and implementation: Completion of a handheld wall radar out of a close study of hardware products, software, parts, structural parts, and other aspects of the test section. In the part of the algorithm, adaptive CFAR(CA-CFAR) detection algorithm is applied to estimate the number of significantly enhanced multi-target detection effect.3. Handheld out of two received radar system design and implementation: Completion of handheld radar products out of two received several key technology researches, and Wi Fi wireless interface has been expanded. In the configuration section, telescoping design used in radar, the radar solves a smaller size and a larger aperture radar this contradiction problem. And completed a prototype of the product and gives the product of the improvement program.
