Problems solved by technology

However, in the application process, there will be various problems: 1) The ground induction coil needs to damage the road surface, and if it is crushed for a long time, the speed measurement will be inaccurate; 2) The video speed measurement is easily interfered by foggy weather, etc.
Also due to its large size, it is not suitable for speed measurement

Abstract

The invention discloses a high-integration Ka-band anti-interference speed measuring radar, which comprises an oscillator, and is characterized in that the oscillator is sequentially connected with afrequency multiplier, a power divider C, a power divider A and a transceiving antenna; the power divider C is divided into two paths, one path is connected with the power divider A, the other path isconnected with a branch line coupler, the power divider A is divided into two paths, one path is connected with the power divider C, and the other path is connected with a power divider B; the power divider B is divided into two paths which are respectively connected with the two frequency mixers, and the frequency mixers are sequentially connected with an amplification filter and an ARM processor; and the branch line couplers are respectively connected with the frequency mixers. The high-integration Ka-band anti-interference speed measuring radar is low in production cost, compact in structure, small in size, high in stability, excellent in performance and reliable in circuit performance, effectively ensures the accuracy of vehicle overspeed detection, and can be widely applied to policesnapshot speed measurement systems.

Description

technical field [0001] The invention relates to the field of speed measuring radar, in particular to a highly integrated speed measuring radar applied in Ka band. Background technique [0002] In recent years, the number of motor vehicles has risen rapidly, and the contradiction between the current situation of traffic management and the demand has further intensified. It is particularly necessary to use the traffic speed measurement system for traffic control. In order to reduce traffic accidents caused by speeding, traffic control systems in various places use many methods to solve them, such as measuring vehicle speed through ground induction coils, video, radar, etc. However, in the application process, there will be various problems: 1) The ground induction coil needs to damage the road surface, and if it is crushed for a long time, the speed measurement will be inaccurate; 2) The video speed measurement is easily interfered by foggy weather, etc. [0003] Radar speed ...
