The invention discloses a method for preventing a vehicle from running a traffic light at an intersection by mistake under an intelligent driving assistance system. The method for preventing the vehicle from running the traffic light at the intersection by mistake under the intelligent driving assistance system comprises the steps of obtaining information of a vehicle running environment by usinga sensor; inputting the information into an ACC function control module so as to obtain a visual field angle alpha for actual judgement; if alpha is larger than or equal to 0, transmitting a positiveor negative accelerated speed request value to a communication module; if the alpha is less than 0, transmitting a negative accelerated speed request value to the communication module; and finally, enabling the communication module to transmit information of controlling a following distance to a vehicle body control unit. According to the method for preventing the vehicle from running the trafficlight at the intersection by mistake under the intelligent driving assistance system, the identification accuracy can be improved, it can be guaranteed that a driver can observe more traffic road condition information, and the risk of running the traffic light by mistake can be prevented.

The invention discloses an AGC adjustment method for satellite-borne interference imaging height gauge based on FPGA. The method comprises the steps of 1, using a current pulse attenuation code to perform ADC sampling, and collecting an echo signal of transmitted pulse; 2, computing a current echo amplitude mean value according to the collected echo signal; and 3, forming multiple sections by division according to an injected expected echo amplitude upper limit value and an injected expected echo amplitude lower limit value, and judging whether the current echo amplitude mean value is positioned in the specified section; if the section where the current echo amplitude mean value is located is the specified section, using the current pulse attenuation code as an attenuation code value applied to echo signal sampling of the next transmitted pulse; and if the section where the current echo amplitude mean value is located is not the specified section, generating the next pulse attenuationcode to serve as the attenuation code value used when the echo signal is sampled at the next time according to a judgment result and the current pulse attenuation code. According to the method, the echo signal amplitude mean value can be quickly adjusted to the proper section.
