A contiguous filter for use with a HF, phase-coherent, storage-type, pulse-doppler radar which employs a spectral compression technique for processing velocity and acceleration signals. A number of parallel channels, each covering a contiguous section of the multiplied doppler frequency band to be covered, are used. Each channel comprises a bandpass filter, an amplifier, a limiter, another bandpass filter and a gate. The gates are sequentially opened to pass a sweeping signal that the signal analyzer, to which the output of the gates is fed, is matching.
