Abstract
Improved radar system performance in a jamming environment is achieved by making a complete frequency analysis of the jamming power entering the radar receiver during each range sweep (once per transmitted pulse) and then setting the frequency of the next transmitted pulse to the value which corresponds to the minimum jamming power measured.
Claims8
In a frequency agile radar, apparatus for transmitting a frequency which corresponds to a low jamming frequency, comprising:
- means for sampling a portion of the input to the radar during the dead time of the radar receiver;
- means for measuring said sampled portion of the input to determine the frequency of the minimum received total jamming power;
- and
- means for controlling the frequency of the signal to be transmitted by the radar on the next pulse to correspond to the frequency of the minimum received total jamming power.
