Abstract:
A method for determining a frequency modulation includes generating a symbol stream that is filtered, with multiple samples per period. Sample values represent samples of the filtered symbols at instants separated by intervals of a fraction of a time period between successive symbols. Samples of I and Q waveforms are calculated from frequency modulating a signal with the sequence of symbols. For each possible set of symbol values on which a waveform depends, an average waveform is produced over all symbol values outside the group; and on which the waveform is not to depend, all waveforms are superimposed within +/−half a period of the center symbol of each group having the same set of values and averaging the superimposed I, Q samples to produce for each group an averaged set of samples and an average waveform. Final I, Q values are stored for subsequent frequency modulation.

Claim (Index 1):
A method for determining a frequency modulation of a continuous wave radar for a vehicle, the method comprising:\n generating a symbol stream comprising a time-sequence of modulating symbols, each symbol belonging to a limited set of symbols having unique numerical values; feeding the symbol stream through one of (i) a shaping and (ii) filtering process to obtain a sequence of shaped or filtered symbols, respectively, comprising multiple sample values per symbol period, wherein the sample values represent samples of the shaped or filtered symbols at instants separated by intervals of a fraction of a time period between successive symbols; calculating, for the sample instants, (I,Q) samples of I and Q waveforms resulting from frequency modulating a carrier signal with the sequence of modulating symbols, wherein each I value is equal to a cosine of resulting instantaneous carrier phases at the sample instants, and each Q value is equal to a sine of the instantaneous carrier phases at the sample instants; for each possible set of values of a group of successive symbols on which a waveform is to depend, producing an average waveform over all symbol values outside the group; and on which the waveform is not to depend, superimposing all waveforms within plus and minus half a symbol period of the center symbol of each group having the same set of values and averaging the superimposed I, Q samples to produce for each group an averaged set of I, Q samples, and an average waveform; and recording final I, Q values to be stored in a memory for subsequent use in producing the frequency modulation in the frequency modulated continuous wave radar.
