摘要： A periphery monitoring radar device includes a transmission unit, a reception unit, a spectrum generation unit, an azimuth calculation unit, an environment determination unit, and a position calculation unit. The transmission unit transmits a combination of transmission signals modulated using a plurality of modulation modes. The environment determination unit determines whether a peripheral environment is a complex environment from the degree of randomness of a frequency spectrum for each modulation mode. The position calculation unit removes, upon the peripheral environment for at least one modulation mode being determined to be the complex environment, at least one azimuth corresponding to the at least one modulation mode from the azimuths respectively calculated for modulation modes to thereby obtain at least one target azimuth that is at least one of the remaining azimuths except for the removed azimuth; and calculates a position of the vehicle based on the at least one target azimuth.

摘要： A mainlobe detection process can include a number of tests that are performed to define when the monopulse antenna system will transition from open loop scanning to closed loop scanning and then to tracking. A hybrid tracking technique is also provided which adaptively discovers and corrects for phase alignment error. Magnitude-only tracking can be performed initially to locate the nulls in the azimuth and elevation ratios and to identify the magnitudes of these ratios at these nulls. Phase tracking can be then performed. During phase tracking, phase corrections can be repeatedly applied to the azimuth and elevation difference channels to correct any phase error that may exist. During this process, the magnitudes of the ratios can be used to determine how the phase corrections should be adjusted. Once the hybrid tracking process is complete, the monopulse antenna system is properly phase-aligned and phase tracking will be correctly employed.

摘要： A radar sensor with a signal generation unit that generates a sequence of output signals for the generation of a radiated radar signal. The radar sensor has a signal receiving unit for the reception and for the processing of reflected radar signals as received signals, which are further processed for the analysis of the received signals. A sequence of voltage signals rising from a starting frequency are generated as output signal. The respective received signals are analyzed by means of Fourier analysis, and the output signals have a modulated starting frequency.
