Jam resistant radar design Modern radars also include low probability
of detection techniques in order to prevent being detected (before any EW can begin). Typical techniques include: A purposeful reduction in peak power Frequency agility along with an increase in
receiver bandwidth (with advanced low loss, low noise floor receivers) sidelobe
Very high gain antennas 55dB above the first
