Angle Dependent Match Filter Design for Circulating Code

Abstract

Circulating code provides a simple way to achieve transmit diversity with stable gain along wide angular coverage, whereas this property is at costs of poor sidelobe signal suppression ability and degraded range resolution. In this paper, an angle dependent match filter combined with slow-time coding is proposed and investigated to solve the above problem. The angle dependent match filter is designed via convex optimization technique to suppress interfering signals from sidelobes with a controllable penalty in the target signal-to-noise ratio (SNR). Then the slow-time coding technique is used to recover range resolution. Numerical experiments are carried out using simulated data. The performance assessments show that the proposed technique is superior in interference suppression and range resolution improvement.
