The key problems of software radio and direct sequence spread spectrum range used in high range radio fuze are discussed. The effects of doppler frequency and carrier's initial random phase are analyzed. A new direct sequence spread spectrum algorithm based on software radio is proposed, by using differential encoding and quadrature demodulating, the effects of doppler frequency and carrier's initial phase on the output of inference filter are eliminated successfully.

Based on the technique of radiate temperature measurement, the author designs a circuit of prismatic decomposition colorimetric radiate temperature measuring. A high resolution A/D converter and measurement range switch technology are adopted to resolve the problem that it has lower radiation power and lower signal sensitivity in the low-temperature stage, while higher signal amplitude and higher need of dynamic range in the high-temperature stage. The technique of the Black Body Furnace demarcates, digital calibration and the quartic curve fitting are applied to correct the sensor and improve its measurement precision.
