摘要： A Doppler radar speed detecting method in which periods of a Doppler signal are measured within a predetermined sampling time, and frequency data corresponding to the thus obtained period data are obtained. Upper and lower limit values are set based on the previous Doppler frequency F(k-1). The frequency data are compared with these limit values. Frequency data within a low region lower than the lower limit value, and intermedaite region between the lower and upper limit values, and a high region higher than the upper limit value are respectively counted in accordance with the comparison. Further, for the frequency data between the lower and upper limits, an integrated value of differences between these data and the previous Doppler frequency is obtained. From these integrated value and the numbers of frequency data, the change from the previous to the present Doppler frequency is calculated. By adding this change and the previous Doppler frequency together, the present Doppler frequency is obtained.

摘要： The invention relates to a transponder for a vehicle identification device in which a radio wave including vehicle information returned from transponders provided in a vehicle is received by an interrogator. The vehicle transponder receives a query radio wave and uses a detection device to generate a previously memorized coded signal train in response to a received wave. The coded signal train varies an amount of bias voltage of the detection device so that a reflection coefficient of the detection device is varied to modulate the reflection wave of the query radio wave and the modulated wave is transmitted back to the interrogator.
