Ka波段雷达前端是作为现有C波段INW雪崩雷达的补充而开发的。在现有的C波段雷达上增加了额外的Ka波段通道，用于探测雪崩的粉末部分，这些粉末部分可能具有造成巨大破坏的高压波。采用GaAs雪崩二极管和MMIC研制Ka波段雷达阵面。TX和RX天线具有椭圆形波束宽度，以适合真实的雪崩几何形状。
Ka-band Radar front-end was developed as a supplement to existing C-band INW Avalanche Radar. The additional Ka-band channel was added to the existing C-band radar for to detect powder fraction of avalanches, which can have high-pressure waves inflicting enormous damages. GaAs IMPATT diodes and MMIC were used to develop Ka-band Radar front. TX and RX antennas have elliptical beam widths for to fit real avalanche geometry.
