A moving target detector (MTD) in a radar system uses corrected weighting coefficients to compensate for pulse stagger effect on transmitted pulses. Transmitted pulses are sampled when the radar is switched to a test mode for determining a correction factor which is used to calculate the corrected weighting coefficients. The radar return signals are processed in the MTD by a finite impulse response (FIR) filter using the stored corrected weighting coefficients calculated for each sequence of transmitted pulses including block stagger and pulse stagger sequences.

A radar system having stagger compensation in a moving target detector comprising: means for transmitting pulses with staggered pulse repetition frequency (PRF); means for receiving return signals from said transmitted pulses; means for storing in said moving target detector predetermined weighting

A radar system having stagger compensation in a moving target detector comprising: means for transmitting pulses with staggered pulse repetition frequency (PRF); means for receiving return signals from said transmitted pulses; means for storing in said moving target detector predetermined weighting coefficients corrected for pulse stagger amplitude and phase errors on said transmitted pulses, said predetermined corrected weighting coefficients being determined during a test mode of said radar system; means coupled to said receiving means and said storing means for filtering quadrature samples of said received return signals of sequences of said transmitted pulses in accordance with said corrected weighting coefficients received from said storing means; and means coupled to said storing means and said transmitting means for synchronizing said corrected weighting coefficients for said filter means with said transmitted pulses.
