Accelerated target detection by scanning post-detection integration

In radar signal processing, PDI (post-detection integration) is widely used to improve the target detection performance). In the conventional PDI, it is assumed that the target is stationary and the Doppler frequency is constant. If the target is accelerated, the target detection performance degrades. To resolve the above problem, in this paper, we propose a new method, scanning PDI, which performs the PDI while compensating the Doppler shift which is caused by the target acceleration. Moreover, we estimate the performance of the scanning PDI by deriving the relationship between the target acceleration and the detection probability of the target.
