Study　on　the　radiation　characteristics　of　infrared　jamming　target　and　the　anti-interference　capability　of　infrared　imaging　system,　through　the　analysis　of　radiation　theory,　the　experimental　study　analyzes　the　change　of　radiation　intensity　over　time,　the　radiation　intensity　of　different　projection　directions　and　different　delivery　amount　over　time,　the　spectral　radiation　characteristics　of　the　jamming　target　and　the　radiation　area　of　the　interference　target　over　time.　Combined　with　the　development　characteristics　of　infrared　imaging　system,　it　provides　the　anti-interference　effective　response　strategy　of　infrared　imaging　system　under　practical　application　condition.　The　results　can　provide　experimental　support　for　enhancing　the　anti-interference　capability　evaluation　of　the　infrared　imaging　system.　©　2024　SPIE.　All　rights　reserved.
