Synthesis and integration can improve the signal-to-noise ratio (SNR) of output signal, thus increasing the signal detection probability and extending the radar range.

To improve the Signal-to-noise Ratio(SNR) and detecting probability of small target in infrared image sequences, a novel method of target detection based on spatial-temporal filtering is proposed.

In the process of target detection, depth bomb fuze will undergo the interference from echo signal of neighborhood bomb that is the primary factor which causes high false-alarm probability.
