The invention discloses a vehicle-mounted radar speed measuring and distance measuring system. The system comprises a microprocessor, a microwave radar sensor, a signal conditioning module, an LCD display circuit, an upper computer communication module and a power supply device; according to the microprocessor, a single-chip microcomputer MSP430F436 is adopted as a core chip; mixing signals outputted by the microwave radar sensor are divided into two paths of input after passing through the signal conditioning module, wherein the two paths of input are respectively inputted into an MCU and anA / D converter; the MCU decides the magnification times of a programmable amplifier and the discharge moment of a power storage capacitor in a peak detection circuit through reading the result of the A / D converter and capturing and counting square wave signals outputted by a voltage comparator in the signal conditioning module; and the MCU also converts obtained frequencies and amplitudes into relative speeds and distance values, and displays the speeds and distance values on the LCD display circuit in real time. With the vehicle-mounted radar speed measuring and distance measuring system adopted, the problems of low precision and high power consumption of a vehicle-mounted radar speed measuring and distance measuring system in the prior art can be solved.
Description
technical field [0001] The invention relates to the field of vehicle-mounted radar, in particular to a vehicle-mounted radar speed and distance measuring system. Background technique [0002] Vehicle radar, as the name suggests, is a radar for cars or other ground-based motor vehicles. Therefore, it includes a variety of different radars based on different technologies (such as laser, ultrasonic, microwave), with different functions (such as detecting obstacles, predicting collisions, adaptive cruise control), and using different working principles (such as pulse radar) , FMCW radar, microwave shock radar). Microwave radar has important commercial significance in automotive radar. [0003] The vehicle-mounted radar speed and distance measurement system in the prior art has the problems of low precision and high power consumption. [0004] Therefore, it is an urgent problem to be solved by the present invention to provide a vehicle-mounted radar speed and distance measurin...
