    Abstract: A forward looking sensor (FLS) has a transmit antenna (52) and a receive antenna (56). The receive antenna (56) is coupled through a low noise amplifier (122) and a single sideband generator (126) to a down-converting mixer (146) which supplies an intermediate frequency signal to a further down-converting mixer (158). The further down-converted signal is supplied to an analog-to-digital converter stage (166) of a digital signal processor (60). The transmit antenna (52) receives a signal for transmission from a voltage controlled oscillator (VCO) (70) in a transmitter circuit (50). The single sideband generator (126) comprises a power divider having an input port coupled to the output port of the low noise amplifier (122), and first and second output ports supplying respectively the input ports of first and second amplifiers (132, 134). The amplifiers (132, 134) have respective control ports to which a synthesized fixed frequency is supplied in quadrature to modulate the received signal. The outputs of the amplifiers (132, 134) are coupled to respective input ports of a quadrature coupler (142) having a first output port at which a filtered, single-sideband signal is provided, and a second, terminated output port.

    Abstract: An automotive forward looking sensor has a transmit antenna (52) that generates a multiple beam pattern (68a - 68m), and a receive antenna (56) that receives in a multiple beam pattern (66a - 66m). The outermost beams (66a,66m; 68a,68m) of the patterns are used as alignment beams and are aimed at approximately 20° in opposite directions from the nominal centre line of the forward looking direction, and are angled down at approximately 45° towards a road surface. With the beams properly aligned, substantially identical Doppler returns are detected. Difference between Doppler returns indicates misalignment.

    Abstract: A forward looking sensor (FLS) has a transmit antenna (52) and a receive antenna (56). The receive antenna (56) is coupled through a low noise amplifier (122) and a single sideband generator (126) to a down-converting mixer (146) which supplies an intermediate frequency signal to a further down-converting mixer (158). The further downconverted signal is supplied to an analog-to-digital converter stage (166) of a digital signal processor (60). The transmit antenna (52) receives a signal for transmission from a voltage controlled oscillator (VCO) (70) in a transmitter circuit (50). A control signal (72) for the VCO (70) is generated in response to the output of a mixer (84), which is supplied with a portion of the transmitted signal from a coupler (82), and a local oscillator signal from a dielectric resonator oscillator (86). The mixer output (92) is linearized by a linearization circuit (80). The linearization circuit (80) has a phase or frequency detector (96) which produces the control signal by comparing a fixed reference frequency signal (98) with a frequency divided signal (106) derived from the mixer output (92). The frequency division is controlled by a counter (100).
