Abstract :
Ubiquitous radio: is a new radar system that provides continuous and uninterrupted multifunction capability within a coverage volume. Continuous coverage from close-in "pop-up" targets in clutter to long-range targets impacts selection of waveform parameters. The CPI (Coherent Processing Interval) must be long enough to achieve a certain signal-to-noise ratio (SNR) that insures the efficiency of detection. This paper analyzes the condition of detection in the case of low SNR, discusses three different cases that would occur during integration and presents a method to determine the CPI. The simulation results show that it is available to determine the CPI for targets detection with SNR as low as -26dB in the experimental system.
