    Abstract: Apparatus and methods for performing automatic gain control in a radar system (20). One embodiment of the system includes an attenuator that controls gain of signals received from a radar receiver (24). A digital signal processor (44) determines coarse gain correction based on digitized noise data for a plurality of channels, dstemimes fine gain correction based on the residual error after the coarse gain, and determines frequency vs. gain curve correction based on the digitized noise data for a plurality of channels and a mathematical model of frequency gain across a noise spectrum for the radar system. The result of the processor is a gain control signal that is sent to the attenuator to perform hardware gain control and a channel specific scale factor for software gain control. In one embodiment, the processor generates the gain contra signal during an inactive scan mode of the radar system.

    Abstract: A first low-noise amplifier is connected to a first receiving processing unit through a first cable and a bypass circuit is provided in parallel to the first low-noise amplifier so as to bypass the first low-noise amplifier. In the case that the intensity of broadcasting signal is more than a predetermined value, when the C/N is more than a first predetermined value and less than a second predetermined value higher than the first predetermined value, the broadcasting signal is transmitted to the first cable through the first low-noise amplifier, and when the C/N is less than the first predetermined value or more than the second predetermined value, the broadcasting signal is not input to the first low-noise amplifier but transmitted to the first cable through the bypass circuit.

    Abstract: An on-vehicle receiving device for promoting distortion reduction, improvement of receive sensitivity, and power-saving effect is provided to increase the receive sensitivity if a C/N(Carrier to Noise) ratio is between the first and second predetermined values, and to prevent deterioration of the C/N ratio if the ratio is less than the first predetermined value as reducing power consumption, then to decrease power consumption as maintaining a large C/N ratio even when the ratio is more than the second predetermined value. The first LNA(Low Noise Amplifier)(22) and the first receiving processor(27) are connected by the first cable(26). A bypass circuit(23) for detouring the first LNA(22) is installed in the first LNA(22), so that intensity of a terrestrial digital broadcasting signal is more than a predetermined value. When a C/N ratio is more than the first predetermined value and less than the second predetermined value higher than the first predetermined value, the terrestrial digital broadcasting signal is delivered to the first cable(26) via the first LNA(22). If the C/N ratio is less than the first predetermined value or more than the second predetermined value, the terrestrial digital broadcasting signal is delivered to the first cable(26) via the bypass circuit(23) without being inputted to the first LNA(22).
