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
