Digital method of detecting pulses of short duration and arrangement for implementing the method |
摘要 |
The invention relates to a digital method of detecting pulses of short duration and an arrangement for implementing the method. A threshold value is generated by means of a statistical procedure which is common in radar engineering, by means of which short pulses to be detected can be differentiated as opposed to long pulses. The method includes sorting a predeterminable number of temporally consecutive signal samples by amplitude and creating a ranking of the signal samples. An associated amplitude value for a predeterminable rank within the ranking is determined and multiplied by a predeterminable weighting factor (k) so that an amplitude threshold value (SW) is generated. All signal samples whose amplitude is greater than the amplitude threshold value (SW) are then marked with a marking signal.
