The bidirectional oversampling imaging detection system solved the difficulties of infrared point target detection
under the traditional single sampling system, effectively improved the image target detection SNR and reduced the
false alarm, and improved the target detection performance. The mathematical modeling and system simulation of
both traditional line scanning method and bidirectional oversampling scanning system proved that under the same
conditions, the detection rate of bidirectional oversampling system is higher than conventional sampling, while the
false alarm rate of bidirectional oversampling system is less than conventional sampling.
