摘要： A circuit for speed measurement of vehicles according to the Doppler-radar principle wherein a Doppler-useful signal is evaluated in a computer to which such signal is infed by means of a threshold value switch. A single sideband modulator is provided, at the input side of which there is supplied the Doppler-useful signal and also a high-frequency signal produced by a high-frequency oscillator. The output side of the single-sideband modulator is connected with the input of a phase-locked loop, the output signal of which is converted into the original frequency band of the Doppler signal by means of a demodulator connected at its output side with the input of the threshold value switch.

摘要： Radar systems that operate in accordance with the crossfeed method require an exact balancing of the individual Doppler frequency evaluation channels in the receiver. According to the invention, a special method is used first to make the amplitude levels in the individual channels equal to one another and then to determine and balance the phase differences between the channels. A radar system using this method is also described.

摘要： A method of checking or testing the functionality of transmitter-receiver reversing switches of pulse Doppler-radar installations for protecting the microwave-receiver component, testing being accomplished by means of a microwave-test signal supplied to the microwave-receiver component between the antenna and the transmitter-receiver reversing switches. According to the invention, the Doppler angle error voltages brought about by such microwave-test signal is measured once with and once without the radar transmitter turned-on, there is formed the difference signal between both of the momentarily measured Doppler angle-error voltages, and when there occurs such a difference signal there is concluded that there is present a defective transmitter-receiver reversing switch.
