摘要： The present invention provides a method and system for transmitting a multi-frequency signal composed of discrete tones of constant envelope parts that are amplified by a bank of fully saturated transmitters operating in their most power efficient mode. After amplification and transmission, the signals are multiplexed in the air as opposed to multiplexing before amplification that allows for more efficient amplification as well. In a preferred embodiment, the system has two or more transmitting antennas, and the method comprises: (a) generating a first signal of a first carrier frequency and a second signal of a second carrier frequency; (b) transmitting the first signal of a first carrier frequency on a first antenna and the first signal of a second carrier signal on a second antenna for a predetermined time period; and (c) transmitting a second signal of the second carrier frequency on said first antenna and a second signal of the first carrier frequency on the second antenna for the predetermined time period. Preferably, the signals are transmitted using an amplifier that is essentially fully saturated.

摘要： A process of determining target parameters of an object within a field of detection of an automotive radar system, the process comprising the steps of: (a) establishing a target range from a sequence of ranges; (b) dwelling on the target range for an initial dwell time to obtain sensor data; (c) determining if the sensor data corresponds to the presence of an object or to the absence of an object at the target range based on probability density distributions of an object being present and being absent at the target range, and if such the determination cannot be made, then repeating steps (b)-(c) until the determination can be made; (d) if the sensor data is determined to correspond to the presence of an object in step (c), then dwelling at the target range for an extended dwell time to obtain additional sensor data for determining the target parameters of the object before proceeding to step (e); and (e) establishing the next of the sequence of ranges as the target range before reiterating steps (b)-(e).

摘要： A radar based sensor detection system comprises a microwave source operative to provide a continuous wave signal at an output. A pulse-former is coupled to the output of the source and is operative to provide at an output a variable length pulse that increases the transmitted energy of the radar system according to the range of object detection. A modulator is coupled to the output of the pulse-former for providing a modulated pulse signal when required. A transmit/receive switch coupled to the output of the modulator is selectively operative between a first transmit position and a second receive position. A transmit channel coupled to the transmit/receive switch transmits the pulse signal when the switch is operated in the transmit position. A receiving channel coupled to the transmit/receive switch receives the modulator signal when the switch is operated in the receive position. First and second voltage multipliers each have a local oscillator input for receiving the modulator signal in the receive position, and each have an input signal port, and an output port. A receiver channel receives a reflected transmitted signal from an object and applies the received signal to the receive signal input ports of the voltage multipliers. An autocorrelator coupled to the output ports of the voltage multipliers correlates the received signal to produce an output signal indicating the detection and position of the object.
