Radar Doppler processing using c.c.d and s.a.w. devices

Combining the attributes of charge-coupled-device analogue signal processors with those of surface-acoustic-wave devices promises a compact and inexpensive way of extracting Doppler frequency information from coherent pulse-radar signals. Experimental tests confirm the feasibility of the technique and point the way to a fairly simple processing module which should be applicable to a range of radar parameters.
