Abstract:
1. A method for detection of wind power installations using a radar installation, the method comprising: a) transmitting a number N of predetermined sequences B b) receiving and processing, by the radar installation, transmission pulses reflected by an object, wherein the processing creates received pulses corresponding to the transmitted pulses, wherein a number R of received pulses are received for each transmission pulse; c) determining a range to the object using a signal delay-time measurement from the received pulses belonging to the sequences B d) cyclically performing a number M of measurement processes in an azimuth direction in an azimuth range, wherein N sequences B e) arranging, in sequence using a predetermined correction term, sample values of Z sequences B f) obtaining a result matrix with R rows and N/Z columns from the range Doppler matrix with R rows and N*K columns using the maximum likelihood estimator, wherein the signal strength, phase and Doppler frequency of the object are known for each cell; g) successively producing two result matrices E wherein a range Doppler cell is marked as a location of a wind power installation if
