Modified Rao test for adaptive subspace detection
IET International Radar Conference 2015, 2015The problem of detecting a subspace signal is studied in colored Gaussian noise with an unknown covariance matrix. In the subspace model, the target signal belongs to a known subspace, but with unknown coordinates. We first present a new derivation of the Rao test based on the subspace model, and then propose a modified Rao test (MRT) by introducing a ...

Rao score tests for goodness of fit and independence
Biometrika, 1991Summary: Rao's score statistic [\textit{C. R. Rao}, Proc. Camb. Philos. Soc. 44, 50--57 (1948; Zbl 0034.07503)] is a standard tool for carrying out hypothesis tests. A unified approach is given which encompasses many common tests. When a suitable group structure is present, it is shown how the derivation of the test statistic can be simplified.

The arm detection based on Rao test method
2007 International Symposium on Intelligent Signal Processing and Communication Systems, 2007Firstly, aim at the different radar echo characteristic of anti-radar missile (ARM) and its aircraft, a correlative canceller is proposed to restrain the aircraft signal through estimating its Doppler frequency. Then based on the assumption of autoregressive (AR) process noise, a detection algorithm is derived to implement the ARM target detection ...

Estimation and Tests for Departures from Rao‐Structured Covariance Matrices
Biometrical Journal, 1987AbstractFor linear models, a measure of departure of a variance‐covariance matrix from Rao‐structure (Rao, 1967) is proposed. Relevant estimation and testing problems are discussed. Illustrative examples are also presented.

Performance analysis of a modified Rao test for adaptive subspace detection
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016The problem of detecting a subspace signal is studied in colored Gaussian noise with an unknown covariance matrix. In the subspace model, the target signal belongs to a known subspace, but with unknown coordinates. We propose a modified Rao test (MRT) by introducing a tunable parameter.

Modified Rao test for distributed target detection in interference and noise
Signal Processing, 2020Abstract This paper studies the problem of adaptive detecting distributed targets embedded in structured interference and colored noise. The signal and interference are assumed to lie in two linearly independent subspaces with unknown coordinates. The relative parameter of the conventional Rao test contains only the signal coordinate, whereas it is ...
